Hmm, FreeBSD (unlike OpenBSD and NetBSD) may be somewhat complicated in this
regard. First, I don't think the default compiler used matters. What does
matter is behavior in certain (many?) respects. E.g. in GNU binutils
ELFOSABI_FREEBSD is treated as equivalent to ELFOSABI_GNU in certain places.
So it may be viewed as a "hybrid"? (Of course there are many(?) other things
where GNU environments are expected to "behave" in certain ways.)

Not sure here.
