[OpenWrt-Devel] [PATCH] kernel: Deactivate CONFIG_COMPAT_BRK

[Hauke Mehrtens]

CONFIG_COMPAT_BRK disables the heap randomization which is only needed
for very old and ancient user space applications, I am not aware that we
run any of these, just deactivate this option for these targets to allow
heap randomization.
