Clean up gprof

[andrew]

Summary

• Remove identical or almost identical headers
• List the architectures where aout.c builds rather than where to not build it
• Enable on all architectures

We switched to ELF in FreeBSD 3.2. which means only i386 ever had a.out (though there were prototypes for FreeBSD/alpha with a.out iirc, that's not relevant here).

This should read simply

.if ${MACHINE_CPUARCH} == "i386"

Crazy question: Do we support building and profiling a.out even at all? Maybe we just drop it entirely?

[andrew]

I have no idea, although if we remove it I think it should be a second change that could be easily reverted if needed.
