branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2017.02.x
grub2 fails to configure when BR2_SSP_ALL is enabled, with the following
configure error:
checking whether -fno-asynchronous-unwind-tables works... yes
checking whether -fno-unwind-tables works... yes
checking for target linking format... unknown
configure: error: no suitable link format found
This can be worked around by enforcing -fno-stack-protector in the
package CFLAGS in a way that overrides the SSP flag, as is already done
for the valgrind package.
Fixes bug #10261.
