I'm looking for an ok on this diff, which sets elf_aux_info(3) flags
for Power ISA 2.06, 2.07, isel, and crypto.  The diff is the same as
I sent last week (12 Jul).

libgcrypt in ports sees the flags and enables crypto acceleration.
SHA256 is slightly faster, and AES128 CBC encryption is over twice as
fast, in accelerated libgcrypt (versus unaccelerated LibreSSL).  nss
and nettle didn't accelerate and will need a patch to start calling
elf_aux_info.  LibreSSL will need some asm.

ok?
