[Buildroot] [git commit] toolchain-buildroot: don't show musl on noMMU platforms

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=ee47352920cd0a89d6b775d489541183b31fb9d1
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

While musl has recently gained noMMU support for the sh2 platform, we
don't support this yet. So for the time being, let's not show musl as
an available C library on noMMU platforms. This is for example
important on ARM noMMU: ARM is supported by musl, but not its noMMU
variants.
