I don't think we have any users that regularly test using a musl OS, so
I guess these problems are to be expected.  (I saw test failures in
string-collate* for instance, which is something where we defer to libc
for sorting, I think.)

It'd be more useful to have reports about these test failures for the
"master" branch instead of emacs-28.1.  Would it be possible for you to
run "make check" there instead?
