I'm porting libvirt to Buildroot (https://buildroot.org/) as a pet
project and musl is one of the supported C libraries. This was the
only compilation error I found with musl.

So far all my run-time tests pass without failure but I'm enabling a
very limited number of features. Other problems may arise as I enable
and test more features.

I'm testing with uClibc-ng too. I will keep you informed about the progress.
