Repeating the generic build with latest git, I get:

So, this time the 3rd MD5 value is similar to the 1st.
May be last time I unplugged the power supply in the middle of the
build, I don't know.
c/s rate in benchmark for generic build is as disappointing as it was
for the 1.7.9 core version:
Benchmarking: FreeBSD MD5 [32/32]... DONE
Raw: 3191 c/s real, 3197 c/s virtual
This is for linux-x86-any:
Benchmarking: FreeBSD MD5 [32/32]... DONE
Raw: 4252 c/s real, 4260 c/s virtual
And this for linux-x86-sse2:
Benchmarking: FreeBSD MD5 [128/128 SSE2 intrinsics 12x]... DONE
Raw: 6524 c/s real, 6537 c/s virtual
So, in current git, sse2 is much faster than any, and generic fails
again to provide a reasonable performance.
