*/builtin.mk: Use ${_CROSS_DESTDIR:U} for build-time file checks.

These are questions about the target system, whose files at
build-time are all relative to ${_CROSS_DESTDIR} if it is defined,
i.e., if USE_CROSS_COMPILE is set to yes.

No change to native builds because ${_CROSS_DESTDIR:U} is empty in
them.  (Possible minor change by adding :Q to ${H_FOO} in command
lines, but if this makes a difference it likely fixes problems.)

Log message:
mpfr: update to 4.2.1.

Changes from version 4.2.0 to version 4.2.1:
- Bug fixes (see <https://www.mpfr.org/mpfr-4.2.0/#fixed> and/or the
  ChangeLog file).
- Improved MPFR manual.
- Configure tests: replaced the test of the link with GMP, in order to
  avoid the use of a function without a prototype (Autoconf issue), as
  this is obsolescent in ISO C. The new test should be more robust.

Log message:
mpfr: update to 4.2.0.

Changes from versions 4.1.* to version 4.2.0:
- The "fondue savoyarde" release.
- Binary compatible with MPFR 4.0.* and 4.1.*, though some minor changes in
  the behavior of the formatted output functions may be visible, regarded
  as underspecified behavior or bug fixes (see below).
- New functions mpfr_cosu, mpfr_sinu, mpfr_tanu, mpfr_acosu, mpfr_asinu,
  mpfr_atanu and mpfr_atan2u.
- New functions mpfr_cospi, mpfr_sinpi, mpfr_tanpi, mpfr_acospi, mpfr_asinpi,
  mpfr_atanpi and mpfr_atan2pi.
- New functions mpfr_log2p1, mpfr_log10p1, mpfr_exp2m1, mpfr_exp10m1 and
  mpfr_compound_si.
- New functions mpfr_fmod_ui, mpfr_powr, mpfr_pown, mpfr_pow_uj, mpfr_pow_sj
  and mpfr_rootn_si (mpfr_pown is actually a macro defined as an alias for
  mpfr_pow_sj).
- Bug fixes.
  In particular, for the formatted output functions (mpfr_printf, etc.),
  the case where the precision consists only of a period has been fixed
  to be like ".0" as specified in the ISO C standard, and the manual has
  been corrected and clarified.
  The macros of the custom interface have also been fixed: they now behave
  like functions (except a minor limitation for mpfr_custom_init_set).

 openscad has PKGREVISION++ because of icu update almost at the same time,
and not packaged since then, so no PKGREVISION++ is necessary, (OK ?)

Log message:
mpfr: updated to 4.1.1

Changes from version 4.1.0 to version 4.1.1

Bug fixes (see the fixed bugs on the MPFR 4.1.0 page and/or the ChangeLog file), \ 
in particular for macros implementing functions.
Improved manual formatting.

gmp,mpfr: Remove CONFIGURE_ARGS flags from builtin.mk as it assumes that
all recursively depending packages can deal with them.
Those packages that need them already add those CONFIGURE_ARGS, at least
pbulk hasn't revealed any issues (thanks jperkin@).
XXX libiconv is in a similar position, so should receive similar
treatment, but at least it only adds the flags if GNU_CONFIGURE=yes
Fixes PR pkg/55487

Log message:
mpfr: update to 4.1.0.

Changes from versions 4.0.* to version 4.1.0:
- The "épinards à la crème" release.
- Binary compatible with MPFR 4.0.*, though some minor changes in the
  behavior of the formatted output functions may be visible, regarded
  as underspecified behavior or bug fixes (see below).
- New --enable-formally-proven-code configure option, to use (when available)
  formally proven code.
- Improved __GMP_CC and __GMP_CFLAGS retrieval (in particular for MS Windows).
- Option -pedantic is now always removed from __GMP_CFLAGS (see INSTALL).
- Changed __float128 to the type _Float128 specified in ISO/IEC TS 18661.
  __float128 is used as a fallback if _Float128 is not supported.
- New function mpfr_get_str_ndigits about conversion to a string of digits.
- New function mpfr_dot for the dot product (incomplete, experimental).
- New functions mpfr_get_decimal128 and mpfr_set_decimal128 (available only
  when MPFR has been built with decimal float support).
- New function mpfr_cmpabs_ui.
- New function mpfr_total_order_p for the IEEE 754 totalOrder predicate.
- The mpfr_out_str function now accepts bases from -2 to -36, in order to
  follow mpfr_get_str and GMP's mpf_out_str functions (these cases gave an
  assertion failure, as with other invalid bases).
- Shared caches: cleanup; really detect lock failures (abort in this case).
- The behavior of the formatted output functions (mpfr_printf, etc.) with
  an empty precision field has improved: trailing zeros are kept in a way
  similar to the formatted output functions from C.
- Improved mpfr_add and mpfr_sub when all operands have a precision equal to
  twice the number of bits per word, e.g., 128 bits on a 64-bit platform.
- Optimized the tuning parameters for various architectures.
- Improved test coverage to 98.6% of code for x86_64.
- Bug fixes.
- MPFR manual: corrected/completed the mpfr_get_str description in order to
  follow the historical behavior and GMP's mpf_get_str function.
- New: optional "make check-exported-symbols", mainly for the MPFR \ 
developers
  and binary distributions, to check that MPFR does not define symbols with a
  GMP reserved prefix (experimental).
- Mini-gmp support: replaced --enable-mini-gmp configure option by
  --with-mini-gmp (still experimental, read doc/mini-gmp).
- A GCC bug on Sparc (present at least in old GCC 4.5.3 and 5.5.0 versions),
  which made several tests fail when TLS was enabled, is now avoided in the
  tests. The MPFR library itself was not affected and normal code using the
  MPFR library should not be affected either. Users and distributions that
  disabled TLS just because of the test failures can safely re-enable it.

all: migrate homepages from http to https

pkglint -r --network --only "migrate"

As a side-effect of migrating the homepages, pkglint also fixed a few
indentations in unrelated lines. These and the new homepages have been
checked manually.
