* lib/cpu-supports.h (gcc_feature_to_glibc_hwcap): Define the
map for all architectures, because for example one can build
and detect and run x86_64 intrinsics in code built with -m32.
This should not add runtime overhead, as mentioned previously
the map resolves at compile time with standard optimizations.
