Couldn't build.  Building gives at least the same failures as -current
used to have:
- openssl has hard-coded AVX asms not supported by old binutils (even in
   FreeBSD-11 IIRC).  Fixed in -current.  Awaiting MFC.
- after turning off openssl, about 20 more things break, including some
   things that shouldn't be optional.  Hacked around in my checkout, but
   only for -current
- something with c+11 for libunwind.  Breaks building -current too.  Hacked
   around in my copy, but only for -current.
Universe builds are much more broken.  No amd64 or i386 kernel builds, due
to hard-coded -msse4 -mpclmul in CFLAGS for aesni.  Perhaps much more, but
the build stops on these flags early.

Please MFC it to all affected branches.
