musl doesn't support the locale things that the locale requirements test, like
localized money and decimal formatting.

The syscat.errcat tests are broken and rely on the libc to return a specific
string in the form of "Unknown error <n>" for unknown errnos when calling
strerror(), which is not defined anywhere and libcs are free to return any
string they want, up to and including "libcxx tests are silly".

Similarly to glibc, musl uses "NaN" to format NaN long doubles, not "nan".
Finally, musl uses "0" to indicate a NULL pointer as %p argument to *printf().
