Log message:
build Mesa with _ISOC11_SOURCE for c11 visibility
autoconf function tests run without --std and have c11 visibility
timespec_get(3), a c11 function is found this way.
With gcc < 4.6 Mesa will build with --std=gnu99 with clang it will
build with --std=c99 and timespec_get() will no longer be visibile.
Further complicating things gcc 4.2 does not recognise --std=c11.
This was not noticed on linux as they build with _GNU_SOURCE which
among other things gives c11 visibility even with --std=c99.
