build: remove -fstack-protector

Browse source 
If gcc is built without libssp support, it loudly fails linking due to
missing __stack_chk_*() helpers. Unfortunately, gcc isn't smart enough to
disable it automatically.

systemd recently got a CC_CHECK_FLAG_APPEND helper to work around such
issues:
  http://cgit.freedesktop.org/systemd/systemd/tree/m4/attributes.m4

I didn't want to add it now, so let's just drop -fstack-protector. If we
want it, we can try adding it later again.

This partially reverts:

      Add some gcc/ld optimizations and magic

All other gcc/ld options are kept.
