toolchain-external: remove musl-cross prebuilt toolchain

The upstream link to download musl-cross prebuilt toolchain is dead [1] and
there no new download location. Also the last prebuilt toolchain use musl
1.1.12 version which is not uptodate (currently 1.1.15).

Remove this support and recommend to use Buildroot toolchain instead.
