I think I have seen this before. ldd sometimes returns the wrong info.
Try "readelf -l" on the program to verify it has no interpreter. I have
reason to believe that it does have musl's interpreter, and you have not
properly installed musl.

Was this really just an elaborate attempt to advertise your favourite

This doesn't say -static in there. Try adding that and see was happens.
musl-gcc essentially just adds a different specs file to GCC, and that
file is not changed based on the choice to have the shared library or
not.
