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. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>

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.
