[testsuite] backport the other half of a patch to 4.1

[Adam Nemet]

The backport http://gcc.gnu.org/ml/gcc-patches/2006-11/msg00573.html
has missed the libstdc++ half of this patch:

libstdc++-v3:
2006-10-29  Joseph Myers  <joseph@codesourcery.com>

	    * testsuite/config/default.exp (${tool}_target_compile): Use
	    v3_target_compile.

gcc/testsuite:
2006-10-29  Joseph Myers  <joseph@codesourcery.com>

	    * lib/target-supports.exp (check_function_available): Declare
	    function before calling.

This leads to 9 PASS->UNSUPPORTED transitions between 4.1.1 and 4.1.2.

OK to checking the other half?  Tested on i686-pc-linux-gnu.
