Patch for libstdc++-v3 cross build on hpux

[Steve Ellcey]

When I added code to libstdc++-v3/configure.in to support cross-builds
with an hp-ux target I lied about the existence of some functions.  It
didn't break anything then because the functions (finite[fl], isinf[fl],
isnan[fl], sincos) weren't used by any libstdc++ code.  That has changed
with a recent checkin so this patch is to remove these functions from
what hp-ux claims to have while leaving them in the linux and netbsd
cross build lists of existing functions.

I do not have write access so if someone could approve this and check it
in I would greatly appreciate it.  It should only affect cross-builds
where the target is hpux and that is what I tested it on.

	* libstdc++-v3/configure.in (HAVE_FINITE*, HAVE_ISINF*, HAVE_ISNAN*):
	Remove definitions in hpux cross-build because these functions do
	not exist on hpux.
	* libstdc++-v3/configure: Regenerate.
