We have math/test-matherr* as generic tests of matherr working with
binaries that specifically use the compat symbol matherr and not with
newly linked binaries. Those don't however attempt to test properties of
specific symbols for individual libm functions.
A change like the present one is not meant to be user-visible for any
newly linked binary, as a legitimate newly linked binary couldn't link
against the matherr compat symbol anyway. And we don't have any attempt
to ensure that old symbol versions of individual libm functions can be
used together with the compat symbol of matherr - just that the compat
symbol of matherr works with one libm function.
