[PATCH 1/3] include/common.h: fix build against musl

Like uClibc version older than (not yet released) 0.9.34 musl does not have
a rpmatch() implementation.
uClibc defines both __UCLIBC__ and __GLIBC__. So first check for uCibc and its
version and then for a non glibc implementation (like musl). Note, musl does
not define __MUSL__.
