gsdx-ogl: compilation fix for old distribution
add automatic archlinux build detection(wx path can not be found otherwise)
use -fabi_version=6 only for GSdx, solve bug with wxwidget
reenable avx build for GSdx
More robust detection of arch64(or any distrib using same path for wxwidget)

gsdx: debug compilation fix

I'm not sure gcc behavior is correct here!
git ignore: linux profiled data
debian: only support SSE2 for the default build
gsdx-ogl: disable ARB_bindless_texture

I have a crash when I try to delete some texture (for example when the simulator is paused)
gsdx-ogl: always set texture parameter

* Avoid bug after a pause
* Not faster anyway
* keep old method only for gl retracer to reduce debugging noise

Remove some old&useless comment
