devel/freebsd-gcc9 at powerpc (for example) : it has the clang vs. gcc vec_step name conflict (for powerpc families): build fails under clang

devel/freebsd-gcc6 and devel/freebsd-gcc9 both need it.
The vec_step identifier has been in use in gcc's
gcc/tree-vect-loop.c for a long time and still is in
use. Going the other way, reserving vec_step for
opencl/altivec for PowerPc's has been in clang for a
long time.

I've had to have local patches for lang/gcc6 and later
and in devel/powerpc64-gcc historically (2017+) because
of my clang-targeting-PowerPc activities and trying
to build gcc versions via clang as part of those
activities. (Of course, some places have patches of
their own now.)
