powerpcspe doesn't support -maltivec according to base r307761.

Shouldn't be a problem if the file built with -mvsx is never called on a CPU
that lacks VSX. Looking at FreeBSD kernel code, PPC_FEATURE_HAS_VSX is always
available when PPC_FEATURE2_HAS_VEC_CRYPTO is.

Is it possible to run FreeBSD powerpc (or only userland) on modern
powerpc64-capable hardware akin to running FreeBSD i386 (or only userland) on
modern x86_64-capable hardware? If so then -mcrypto -maltivec usage is correct
even on 32-bit powerpc.

At least lib/freebl/gcm-ppc.c (with USE_PPC_CRYPTO defined) builds fine with
Clang -target powerpc-unknown-freebsd13.0.
