Subject: [PATCH 1/2] Do not pass host compiler sanitization flags on to linker
 testsuite.

	* Makefile.am (CFLAGS_FOR_TARGET): Define as a copy of CFLAGS but
	without any sanitization options.
	(CXXFLAGS_FOR_TARGET): Define as a copy of CXXFLAGS but	without
	any sanitization options.
	(check-DEJAGNU): Pass CFLAGS_FOR_TARGET and CXXFLAGS_FOR_TARGET
	as CFLAGS and CXXFLAGS respectively.
