   1 fix undefined macros in musl
   2
   3 musl does not define glibc-specific macros, so use a simple version of
   4 the macro when it is not defined.
   5
   6 This is very inefficient, however, but copying the code from glibc is
   7 not really possible because it is LGPL while libselinux in Public
   8 Domain, and we want to avoid license propagation, so this macro is
   9 completely written from scratch, and non-optimal.
