--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
This has been discussed over and over again.  This is an issue in the libc and
not in GCC.  In your case in libmusl.
Glibc has a similar bug and been discussed how to fix it.
The way Glibc is going to fix it (though it has not yet) is that libpthread.a
will be really just include one object file which includes all of the pthread
library.

libmusl should fix it a similar way.
