I've read something about Gentoo hardened profile and found this:
1) -O3 optimization breaks stack smashing protection
2) SELinux prevents mprotect() from setting execute permissions on memory block

ioquake3 compiled with -O2 shouldn't trigger stack smashing protection anymore.
However, you'll have to disable SELinux mprotect() changes or compile with
`make HAVE_VM_COMPILED=0` which will make everything _REALLY_ slow.

Quake3 uses QVM files as dynamically linked libraries containing game code. QVM
uses platform indepent pseudo-RISC code. It must be compiled into native
instructions during map load. The engine must then set execute permissions to
be able to use the compiled bytecode.
