musl runs only on Linux:

What are musl’s dependencies?
Linux 2.6 or later. Earlier versions will suffice for running most simple single-threaded programs, but due to bugs and conformance issues at the kernel level, musl is not offically supported on earlier kernels.

TLDR: if it doesn't support OpenGenera, it is crap.
