musl: fix gethostbyname_r/gethostbyaddr_ selection
To fix conditional selection of the actually available gethostbyname_r and gethostbyaddr_r, we replace __GLIBC__ with __linux__. @zenhack tested this to work with gcc and clang targeting glibc, uclibc, musl, and bionic. The proper way to check this is through configure.in.
