configure.in: Fix cross compiling math routines.

2001-09-10  Benjamin Kosnik  <bkoz@redhat.com>

	* configure.in: Fix cross compiling math routines. Correct
	comments for cross compiling and limits. Add floating point math
	routines found in newlib.
	* configure: Regenerate.
	* acconfig.h: Add macros.
	* config.h.in: Regenerate.
