musl is very linux specific in many parts, e.g. open read write etc map to system calls. But it's standard C functionality like malloc, *printf, strtok, ... are very compact, comparable to newlib, but IMHO a lot easier to understand any with way better design (e.g., no dynamic memory if not needed).

RIOT only uses a subset of the C library anyways. Just porting musl won't give us fork(), but the same is true for newlib.
