[PATCH libevdev] build: remove -fstack-protector

[David Herrmann]

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.

Hi Peter

This actually breaks the ostree build.gnome.org build, so it'd be nice to see
this applied upstream. It's just a partial revert of:
  43752ec17d09b132621a86f5cbc546ca6ab9e977

Should be good to go.
Thanks
David
