User now can choose CPU type: generic or jitc_x86 (the last one is for x86 only thougth). Added OPTIMIZED_BUILD option, since PearPC is rather slow and it would be nice to use optimized CPPFLAGS to make it a little bit faster.
State Changed From-To: open->closed Committed, thanks! I decided to go with WITH_OPTIMIZED_CFLAGS which is quite common across the tree.
