It's linking against the wrong libc, the one from the FreeBSD-10 host
system, which does not have utimensat():

There should probably be a --sysroot flag in there, pointing to the
${WORLDTMP} built during the earlier stages.
For some reason, this flag is not added for gcc, in Makefile.inc1. No
idea why that was done.
