What should be done, instead of this musl specific hacks, is to add
configure checks for the features that are not supported on musl and
uses these as criteria for disabling the testcases. This will work
correctly for any libc implementaion and the testcases will be enabled
automatically if musl decides to actually implement anything that is not
supported at the moment.
