FreeBSD does not use /proc anymore and has it disabled by default.

For !Win32 systems we could rely on the -march settings of the processor.
According to the manual, the GCC specifies MMX and SSE/SSE2/SSE3 for
several archs, so we just have to test on them. For Win32 I just know about
the CPUID hacks, but that's only interesting for runtime checks.
