+fix undefined macros in musl
+
+musl does not define glibc-specific macros, so use a simple version of
+the macro when it is not defined.
+
+This is very inefficient, however, but copying the code from glibc is
+not really possible because it is LGPL while libselinux in Public
+Domain, and we want to avoid license propagation, so this macro is
+completely written from scratch, and non-optimal.
