Pre-generate the optimized x86 crypto code and check it in rather than
depending on perl at build time. Makefile.asm is a helper for after the
next import.
With my cvs@ hat on, the relatively small repo cost of this is acceptable,
especially given that we have other (much bigger) things like
lib*.so.gz.uu checked in under src/lib/compat/*.
