Subject: [PATCH] libstdc++: testsuite: adjust name_fortify test for
 pre-defined _FORTIFY_SOURCE

Otherwise we get failures with toolchains that have _FORTIFY_SOURCE
defined already to a different value like 3.

libstdc++-v3/ChangeLog:

	* testsuite/17_intro/names_fortify.cc: Undefine _FORTIFY_SOURCE.
