A partial workaround for lang/gcc14 building on/for armv7, given STANDARD_BOOTSTRAP hitting some FreeBSD __aeabi_* symbol issues

FreeBSD has not and does not support all the __aeabi_ prefixed
symbols to make everything work for all the lang/gcc* .

It has gotten to the point that for lang/gcc14 (so modern) that
the likes of:

__aeabi_unwind_cpp_pr0
__aeabi_unwind_cpp_pr1
__aeabi_unwind_cpp_pr2

lead to the likes of:

/usr/local/bin/ld: a.out: hidden symbol `__aeabi_unwind_cpp_pr0' in /wrkdirs/usr/ports/lang/gcc14/work/.build/./prev-gcc/libgcc_eh.a(unwind-arm.o) is referenced by DSO

when attempting a build of lang/gcc14 for:

OPTIONS_DEFAULT_armv7= STANDARD_BOOTSTRAP

# find /wrkdirs/ -name config.log -exec grep -q __aeabi_unwind_cpp_pr0 {} \; -print | more
/wrkdirs/usr/ports/lang/gcc14/work/.build/libdecnumber/config.log
/wrkdirs/usr/ports/lang/gcc14/work/.build/libbacktrace/config.log
/wrkdirs/usr/ports/lang/gcc14/work/.build/libiberty/config.log
/wrkdirs/usr/ports/lang/gcc14/work/.build/lto-plugin/config.log

Note: The poudriere log file ends up instead reporting the likes of:

checking for library containing strerror... configure: error: Link tests are not allowed after GCC_NO_EXECUTABLES.

So: Giving no clue about the specifics.

Going in the direction of instead having:

#OPTIONS_DEFAULT_armv7= STANDARD_BOOTSTRAP

so that gcc is not used at all, the "jit" in:

LANGUAGES:=     c,c++,objc,fortran,jit

prevents having the system clang/clang++ do all
the build: after the early stages, gcc/g++
depends on library coding conventions specific
to gcc/g++ and clang/clang++ based builds do
not follow those conventions in libc++ or such.
(Poisoned names are detected and stop the build.)

As I do not need jit, I do the following in
order to have lang/gcc14 build on/for armv7
(and, presumably could for armv6 as well) :

# git -C /usr/ports/ diff lang/gcc14/ | cat
diff --git a/lang/gcc14/Makefile b/lang/gcc14/Makefile

(I do not show my disabling of install-strip use,
which is done for other reasons.)

At least for now that allows me to have lang/gcc14
other than for the jit language that I do not use.
But gcc14 or g++14 is not involved in producing
that gcc14 and g++14 .
