libgmp: remove trailing whitespace

libgmp: suppress lint warnings about int/size_t mismatch

The cases where numbers have 4 GB of precision are probably rare.

libgmp: clean up LINTFLAGS

Now that gmp-impl.h includes <stdlib.h>, defining alloca is no longer
necessary.

libgmp: fix unwarranted ignored error on 'make clean'

rmdir: dummy: No such file or directory
*** Error code 1 (ignored)

libgmp: suppress a few lint warnings

Instead of erroring out due to the unknown function alloca, lint now
warns about a pointer/integer mismatch since it wrongly assumes that all
__builtin functions

libgmp: suppress a few lint warnings

Instead of erroring out due to the unknown function alloca, lint now
warns about a pointer/integer mismatch since it wrongly assumes that all
__builtin functions return int. The warning is still better than a
failing build though.

Patch the build script and toolchain to allow passing through
HOST_CPPFLAGS, HOST_CXXFLAGS, but not LIBRARY_PATH because it breaks
the build. These variables are necessary to support building NetBSD

Patch the build script and toolchain to allow passing through
HOST_CPPFLAGS, HOST_CXXFLAGS, but not LIBRARY_PATH because it breaks
the build. These variables are necessary to support building NetBSD
from a GNU Guix or NixOS host, where /usr/include, /lib, and all
but /bin/sh do not exist. In many cases, support for HOST_CPPFLAGS
was incomplete. From Ryan Sundberg

add missing sources needed by new mpfr/mpc.

updates for GMP 6.1.2 and most platforms. run tested on i386, amd64,
sparc sparc64, earm, ofppc and mips64eb. build tested on most.

remove the earm* variants as they're now the same as the arm* on

move the GMP_MACHINE_ARCH definition into external/lgpl3/gmp/Makefile.arch.
soon to be GMP 6 allows us to have only two arm copies.

Add -DPIC for PIE builds so that we can avoid text relocations.

When copying an .OBJDIR file, rm -f first.

Arguably there should be some general mechanism, but there isn't yet,
and I hit a build failure at

cp ${.CURDIR}/arch/${GMP_MACHINE_ARCH}/config.m4 ${.OB

Arguably there should be some general mechanism, but there isn't yet,
and I hit a build failure at

cp ${.CURDIR}/arch/${GMP_MACHINE_ARCH}/config.m4 ${.OBJDIR}/config.m4

because my source tree is mode 444, and hence my previously-copied
config.m4 was too.

make trialdivtab.h depend on the Makefile.

consolidate the trialdivtab.h generation code.

Enable warnings on sparc64 again

Disable parentheses checks since libgmp doesn't pass them.

Make warnings non-fatal on sparc64.
Warings reported upstream.

updates for GMP 5.1.3, and new build files for most platforms.

always compile GMP and MPFR as ARM

Use armv[4-7] to be consistend

If MACHINE_ARCH contains armv[467], use arm instead.

collect common rules in the shared Makefile, this propagates the .OBJDIR
fix done for i386 last year to all other ports

Deal with optional HAVE_GCC.

allow LIBISPRIVATE to be overriden, and install everything again.
helpful for mknative-gcc.

Requires -Wno-unused-value -Wno-tautological-compare when building with
clang.

build GMP, MPFR and MPC as private libraries just for GCC. don't
install the headers or librarys into the system.

someone who really cares could make them shlibs again and have them
installed into

someone who really cares could make them shlibs again and have them
installed into eg, /usr/lib/gcc. not convinced it is worth it.
