This port covers an end-of-life version of GCC and is in the tree solely
to support the devel/xtensa-esp32-elf port. Since that one now is limited to amd64 and i386, follow with our own ONLY_FOR_ARCHS setting. This simplifies this port a fair bit and avoids building on amd/aarch64 and powerpc* platforms.
