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.
