Because Buildroot passes its own CFLAGS/LDFLAGS, this was overriding the ones from the package Makefile, leading to build failures because -fPIC was no longer being passed. This commit fixes that by adding a patch that allows to keep the package CFLAGS while passing additional ones through the make command line. While doing this, it also removes a few hardcoded optimization and hardening flags, leaving it to Buildroot to decide whether they should be passed or not. This makes the workaround for stack protector no longer needed.

This also removes a number of hard-coded CFLAGS, leaving it up to the
|
|
user to pass appropriate optimization/hardening flags.
