From: Hauke Mehrtens Date: Sun, 2 Apr 2017 15:40:43 +0000 (+0200) Subject: binutils: fix build with host gcc < 4.9 X-Git-Tag: v19.07.0-rc1~6698 X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=efb22b6f06d44bd156ea42d39779dabd356c7181;p=openwrt%2Fstaging%2Fhauke.git binutils: fix build with host gcc < 4.9 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.
