[LEDE-DEV] [PATCH] binutils: fix build with host gcc < 4.9
Hauke Mehrtens
hauke at hauke-m.de
Sun Apr 2 08:40:43 PDT 2017
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 at hauke-m.de>
---
I would also like to add this to lede-17.01.
Should I better upgrade to binutils 2.28 in master branch?
