scripts: ext-toolchain: add support for musl

Openwrt now supports only glibc and musl. Add support for musl and rework the libc check to handle the new config flags and correctly compile package basend on that. Signed-off-by: Christian Marangi <[email protected]> (cherry picked from commit 7be01fe13b4517e5edb8a4818f437d60144cdcb4)
