Impossible to use from Awesome WM due to the context_new function implementation being overriden by libselinux.so.1

But:

Seems like this function overrides the one from this library: https://www.mankier.com/3/context_new.

The fix would be to replace #define LUA_MOD_EXPORT extern (extern on defined functions doesn't make sense anyway, AFAIK) with #define LUA_MOD_EXPORT __attribute__((visibility("default"))) and to add -fvisibility=hidden to CFLAGS in the Makefile.
