math: Replace RMD160 checksums with BLAKE2s checksums

All checksums have been double-checked against existing RMD160 and
SHA512 hashes

Log message:
various fixes for arm64 big endian support.

most of these simply extend matching from "aarch64" to \ 
"aarch64eb"
in various forms of code.  most remaining uses in pkgsrc of
"MACHINE_ARCH == aarch64" are because of missing aarch64eb support,
such as most of the binary-bootstrap requiring languages like rust,
go, and java.

no pkg-bump because this shouldn't change packages on systems that
could already build all of these.

Log message:
*: Convert broken sourceforge HOMEPAGEs back to http

Log message:
all: migrate several HOMEPAGEs to https

pkglint --only "https instead of http" -r -F

With manual adjustments afterwards since pkglint 19.4.4 fixed a few
indentations in unrelated lines.

This mainly affects projects hosted at SourceForce, as well as
freedesktop.org, CTAN and GNU.

Log message:
Fix indentation in buildlink3.mk files.

The actual fix as been done by "pkglint -F */*/buildlink3.mk", and was
reviewed manually.

There are some .include lines that still are indented with zero spaces
although the surrounding .if is indented. This is existing practice.

Log message:
Use ${WRKDIR}/tmp for temporary files instead of $(mktemp -d)

This is more portable.

As suggested by joerg@.

Log message:
Fix local privilege escalation when building math/lp_solve

This still requires $TMPDIR (or /tmp) to be mounted with "exec", but now
respects $TMPDIR.

Log message:
Honor LDFLAGS. Fixes RELRO build.

Log message:
Update to lp_solve_5.5.2.3 and indicate a 64-bit platform for aarch64
Fix isnan() checks to declare main() returning 'int' and use floating
argument to isnan() avoiding recent (gcc 5) compiler noise.

Since last update:
../../.. version 5.5.2.1
- fixed a small error in new and improved MIP_stepOF function to find integer \ 
solutions.

../../.. version 5.5.2.2
- For integer models with semi-cont variables it happened sometimes that a message
  "fillbranches_BB: Inconsistent equal-valued bounds for ..." occured \ 
and that the semi-cont condition
  was not respected.
- New functions added: get_accuracy to get the numeric accuracy after solve.
- New functions added: set_break_numeric_accuracy, get_break_numeric_accuracy to \ 
let lp_solve return ACCURACYERROR
  instead of FEASIBLE when numerical accuracy if worse then the provided values.
  In the past, lp_solve only returned a non-optimal status in case of very \ 
severe numerical instability.
  Now it will return already ACCURACYERROR when it finds a relative inaccuracy \ 
of 5e-7
- When reading a model from the lp-format and important issues are detected such \ 
as already bounds on variables being overruled
  later with for example a bin keyword, this is now reported in the default \ 
verbose level such that this is seen easier.

08/05/16 version 5.5.2.3
- For some models with integer variables, lp_solve did not find the most optimal \ 
solution.
