[patch] move libstdcxx_flags near where it's used

[Nathanael Nerode <neroden@doctormoo.dyndns.org>]

Patch to top level configure to relocate the defintion of
libstdcxx_flags.

It's only used in one place in all of configure and configure.in, and it
was defined WAAAY above that place.  This was confusing me for a long
time, since I thought there must be a reason for this.  But there
wasn't. (This will break my first reorg patch, but if it's accepted
I'll resumbit it without that part).

Tested on i686-pc-linux-gnu, no changes.

	* configure.in: Move definition of libstdcxx_flags
	right above usage, rather than waaay earlier.
