There's a better fix: You can see in m4/ldexpl.m4 that users of the
'ldexpl' module must be prepared to link with libm. Therefore there is no
point in trying to avoid libm in ldexpl.c. I'm applying this:

        * modules/ldexpl (Depends-on): Add isnanl, remove isnanl-nolibm.
        * lib/ldexpl.c: Undo last change.
