@lang/gcc14: Add changes to make this build on NetBSD/macppc 11.0_RC6.

This pulls over changes to config/rs6000/ and gcc/config.gcc from
our in-tree gcc instance of gcc14, while preserving existing Homebrew-
related changes to gcc/config.gcc.

The most important fix is that on NetBSD/powerpc, -msecure-plt is enabled
by default, so that resulting executables can be run with PAX_MPROTECT
active.  Otherwise, we end up with executables with sections which have
both "write" and "execute" turned on, which PAX_MPROTECT rejects.  Ref.
the entries for .plt and .got sections in "readelf -a".

Fixes PR#60439.

Bump PKGREVISION for both gcc14 and gcc14-libs, to adhere to rules in comments,
even though this *should* be a single-arch build fix, since I had to merge
the patch to gcc/config.gcc.

Carry over changes from in-tree gcc in an attempt at
making this build on NetBSD/powerpc.
