I am not sure it is a good idea to backport this patch to stable
branches, as it add new symbols and a dependency between libm and libc.

In practice that causes issues if a binary started using the old libc
starts to dlopen a library which uses libm. It requires the user to
restart all processes immediately after the upgrade, I am not sure
it's something we want to require in a stable branch.
