lang/gcc12: Add comment to existing patch

Add a comment to files/patch-libgcc_unwind.inc to remember when it will
get obsolete, i.e. once all supported FreeBSD releases include commit
22e564c74eb20e14bd93fd9fdde20e38a29cfcf1.

lang/gcc12: Fix SIGBUS depending on CPUTYPE

Compiling GCC with some CPUTYPE values (e.g. broadwell) result in
breaking some applications (e.g. math/octave, cad/freecad), sending a
SIGBUS.

The issue is due to GCC generating instructions that require variables
to be aligned in memory on certain CPUs. Our libthr does not have the
required alignment so these CPUs fail to execute these instructions.

The patch disables the generation of such instructions.

lang/gcc*: disable building of libssp

For today's FreeBSD 14 and earlier, libssp is a nop because nothing on
FreeBSD will be referencing these headers or lib.  On FreeBSD 15, it
actively breaks building with FORTIFY_SOURCE enabled and it's not worth
trying to make it work- the potential for GCC improvements comes from
the __builtin_object_size enhancement, not from these headers.

lang/gcc12: install ISO_Fortran_binding.h in a separate directory

ISO_Fortran_binding.h is sometimes needed for the support of Fortran
2018, e.g. MPICH must find it to build mpi_f08.mod.

ATM it is installed in a directory depending on $CONFIGURE_TARGET with
a complex path, and it is not possible to point CFLAGS towards this dir
because other headers (like stdatomic.h) would conflict with those from
the system.

Therefore create a new directory /usr/local/include/gcc12 to install
this header.
