recent coreutils (gnulib) assume yes when cross-compiling
for gnu (glibc), but don't know about musl.
For coherence, just set the result to yes for both.
Note that the old coreutils (from meta-gplv2) doesn't
assume anything and instead that recipe hard-codes to yes.
So behaviour with yocto when using meta-gplv2 is actually
better than when using the latest version (when using musl).
This patch rectifies this shortcoming.
