Log message:
libtool: Unbreak the 2.4.7 update.

The main issue is that the configure script was generated with a different
version of autoconf compared to upstream, and hardcoded CC='cc -std=gnu11'
which broke inferred tag detection, as well as likely causing other issues
elsewhere.  Generated patches _must_ use the same version as upstream so that
diffs can be reviewed for changes.

While here remove patches for MirBSD and MidnightBSD.  MirBSD was discontinued
many years ago, and support for MidnightBSD was already included upstream.
This significantly simplifies our patches and helps to identify issues.

Bump PKGREVISION of libtool-base and libtool-fortran.

Log message:
libtool*: update to 2.4.7

* Noteworthy changes in release 2.4.7 (2022-03-16) [stable]

** New features:

  - Libtool script now supports (configure-time and runtime) ARFLAGS
    variable, which obsoletes AR_FLAGS.  This is due to naming conventions
    among other *FLAGS and to be consistent with Automake's ARFLAGS.

  - Gnulib testsuite is enabled and run during 'make check'.

  - Support the Windows version of the Intel C Compiler (icl) in
    libtool script.

  - Pass '-fsanitize=*' flags for GCC and LLVM, and '-specs=*' for GCC
    to linker.

  - Pass '-Xassembler=*' and '-Wa,*' flag to compilers and linkers.

  - The variable 'FILECMD' with default value of '/usr/bin/file' was used to
    replace existing hard coded references to '/usr/bin/file'.

  - Add MidnightBSD support.

** Important incompatible changes:

  - Libtool changed ARFLAGS/AR_FLAGS default from 'cru' to 'cr'.

  - Do not pass '-pthread' to Solaris linker.

  - 'libtool' and 'libtoolize' scripts now use '#! /usr/bin/env sh' shebang.
    Previously '#! /bin/sh' was used, which presents challenges for
    containerized environments.

** Bug fixes:

  - Fix significant slowdown of libtoolize for certain projects (regression
    introduced in 2.4.3 release) caused by infinite m4 macro recursion.

  - Mitigate the slowdown of libtool script (introduced in v2.4.3) caused by
    increased number of calls to '$SED $sed_quote_subst' (bug#20006).

  - Properly parse and export TLS symbols on AIX.

  - Various bug fixes surrounding use of 'sed'.

  - Darwin systems set proper "allow undefined" flag on OSX 11, and
    PowerPC 10.5.

  - Removed some deprecated tests related to 'Makefile.inc' files.

*: recursive bump for perl 5.34

Log message:
PR pkg/53086

Fix the configure code that removes spaces in "-L /some/path" etc.

Log message:
Update libtool packages to 2.4.6.

Changes since 2.4.2 are too numerous to mention, with over 4,700 lines
in the ChangeLog file.  However, this release does at least fix a large
number of build failures on SmartOS, and doesn't appear to cause any
obvious regressions in bulk builds performed by Joerg and myself.

Some pkgsrc cleanups while here, including merging the MirBSD patches
correctly.  It couldn't be made much clearer how to properly integrate
patches here to ensure they are not lost.  Next time you might not be so
fortunate!
