There was a small thinko: If frexpl exists in libm but not in libc, gnulib's
function must be called rpl_frexpl, otherwise (in the case the gnulib code
is built into a shared library) libm's function may in some cases take
precedence.

        * m4/frexpl.m4 (gl_FUNC_FREXPL_NO_LIBM): Set REPLACE_FREXPL if frexpl
        was not found in libc.
        * m4/printf-frexpl.m4 (gl_FUNC_PRINTF_FREXPL): Likewise.
