binutils: fix build with host gcc < 4.9

Browse Source 
binutils 2.27 checks if the target compiler supports -Wstack-
usage=262144, and also uses this setting for the host compiler. If the
host compiler is gcc < 4.9 binutils build will fail. This backports 2
commits which are fixing this problem for binutils 2.28.

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.
