rkcommon fails to cross build from source when building on amd64 or
arm64 for something other than amd64 or arm64, because it detects the
SIMD feature based on the build architecture while it should be
considering the host architecture. The attached patch fixes this. It
also widens the matching such that SIMD is enabled on all architectures
with those CPUs such as hurd-amd64 or musl-linux-arm64 as I think this
was the original intention. Please consider applying it.
