Hi all,
I'd like to commit this patch to trunk.
It is FreeBSD only.
If nobody objects I'll commit it within two days.
Thanks,
Andreas

* config/rs6000/freebsd64.h (ELFv2_ABI_CHECK): Add new macro.
(SUBSUBTARGET_OVERRIDE_OPTIONS): Use it to decide whether to set
rs6000_current_abi to ABI_AIX or ABI_ELFv2.
