Executable stack #95

* Mupen64Plus version: 1.3, head

Mupen64plus uses an executable stack. Linking with -Wl,-z,noexecstack does
not solve the problem.

Naturally, PaX is not amused:

Tail of Mupen64 console output:

Starting r4300 emulator

This is a feature, not a bug.  The executable stack is required for the dynamic
recompiler; that's how it works.  If you do not use the dynamic recompiler for 
the
r4300 core then you shouldn't have this problem.
