pcsx2: linux: take some margins for the height of font (avoid top/bottom cut)

cmake: 
* disable fomit-frame-pointer which cause crash with gcc-4.6 (it was not enabled by default but now I'm sure people will not enable it ;) )
* Try harder to pick the 32bits configuration for wx in a 64bits environment (opensuse/fedora).
