Yeah, after looking at its effects I started working on it.
It only moves out the profiles, which I really expect not
to make any performance difference.
.rodata size reduced by 3264 bytes, .bss size reduced by
312416 bytes (on x86_64).
While I can't imagine that I could have messed it up, I'd appreciate a
quick verification of the Makefile part.
