No, it'll be a bit more work.  The extra function added to DES_bs_b.c
will also need to be added to the assembly files.  I might get to that

Looks good to me given that MD4 has remained the same (not vectorized)
and that this is a generic build.  One of the next steps (for this
format) is to switch to using sse-intrinsics.c code for MD4.
