| 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. |
