commit: https://git.buildroot.net/buildroot/commit/?id=956754262d44a9e3658093c8dd429cadf258d7ea
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2018.11.x
The configure script passes -U FORTIFY_SOURCE -D FORTIFY_SOURCE=2 by
default, which conflicts with BR2_FORTIFY_SOURCE_1 as -Werror is used:
<cross>-gcc .. -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=2 .. -D_FORTIFY_SOURCE=1
<command-line>:0:0: error: "_FORTIFY_SOURCE" redefined [-Werror]
Disable this so the FORTIFY_SOURCE flags in TARGET_CFLAGS (if any) is used
instead.
