I now have problems building gnu/lib/libobjc. When using Clang, gcc is
still used to build gnu/lib/libobjc (see "XXX: clang cannot compile
libobjc yet"), but gcc core dumps at this stage on two different
computers, using the same CFLAGS "-O2 -pipe -march=native" :
pid 38850 (gcc), uid 0: exited on signal 11 (core dumped)

%clang -v
FreeBSD clang version 2.9 (trunk 126547) 20110226
Target: x86_64-undermydesk-freebsd9.0
