+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__.
