fpending: fix regression on DragonFly BSD

Commit 3f5bf99e claimed that it is safe to declare __fpending twice,
but in reality this caused a regression on Dragonfly BSD.  Reported by
GW in <https://lists.gnu.org/archive/html/bug-m4/2013-11/msg00000.html>,
<https://lists.gnu.org/archive/html/bug-gnulib/2013-11/msg00022.html>.

* m4/fpending.m4 (gl_FUNC_FPENDING): Check for declaration.
* lib/fpending.h (__fpending): Don't declare twice.
