Really? Ubuntu provides them, maybe you should complain to your
distro vendor :-)
Anyway, I did a compile test of everything with --static and it
does turn out to be busted:

This is because we seem to have lost the trailing "-lm -lz"; here's
the tail end of the link command from a build on master for
comparison:
