configure.ac: Introduce HAVE_ARM_ASM/HAVE_AARCH64_ASM and the -D flags.
I've been trying to get away without these conditionals in vc4's NEON
code, but it meant compiling extra unused code on x86, and build failing
on ARMv6.
v2: Use the _arm/_arm64 flags to simplify detection (suggested by Rob),
but hide the _arm version under ARCH_ARM_HAVE_NEON to keep from trying
to build this stuff for armv5te.
