system-hacks: define __GNUC__ for FreeBSD

FreeBSDs system headers contain unconditional usage of
macros like __aligned(x), which are only conditionally defined
in sys/cdefs.h (conditional on __GNUC__ or __INTEL_COMPILER).

Bug in FreeBSD, but as work-around we can define __GNUC__ which
picks up these defs.

[This also moves back the glibc defines we had before into the
non-BSD ifdef branch]
