musl does not define glibcisms, so we are missing some macros.
Define what we need in case the macro is missing. We're using a dumb
implementation, which is rather slow, to avoid copying from glibc, to
avoid propagating the LGPL to libselinux, which is Public Domain.
Fixes a bunch of autobuild failures:

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.
