What prefix is musl-gcc installed in? And have you done anything to
modify it or added additional include paths for it? The above symlinks
don't make sense for a typical out-of-the-box installation. I suspect
you've somehow gotten -I/usr/include added to the CFLAGS during build
(either doing it yourself, or as a result of a broken build script) if
adding symlinks to /usr/include made a difference, in which case you
may be using glibc's headers, not musl's, and thus getting broken
results.
