WIP Linux, cpu generic

I wonder if I can recompile linux programs for 32-bit and 64-bit generic . Then I would not have to recompile for every platform. https://gcc.gnu.org/onlinedocs/gcc-4.6.0/gcc/i386-and-x86_002d64-Options.html#i386-and-x86_002d64-Options -mtune=generic;

mtune=native worked, on ARM system
