musl is a libc implementation. As such it contains all standard C
headers and all POSIX functions. In order to use the C++ standard
library with musl, however, you require an implementation of the C++
standard library. libcxx has, to my knowledge, been the most popular
choice to go along with musl, though GCC seems to like its libstdc++
more. I am sure a search engine will counsel you further in this matter

musl can be cross-compiled with the standard options for
cross-compilation. You compile a cross-gcc (and its libgcc) for the
target you want, then compile musl with that cross-gcc, then compile g++
with musl, and then that somehow already contains a libstdc++, or else
you use libcxx. Again, I suggest a search engine.
