This still doesn't describe how upstream conflates 32bit and 64bit
platform variants into a single macro. Notice the error message from
failed attempt to cross-compile with the --enable-runtime-cpudetection
is different between really not supported architecture like sparc64 and
maybe supported powerpc64.
ppc() {
case "$host_arch" in
ppc*|powerpc*) return 0;;
*) return 1;;
esac
}
[...]
if test "$_runtime_cpudetection" = yes && ! x86 && ! ppc; then
die "Runtime CPU detection only works for x86, x86-64 and PPC!"
