[PATCH] x86-64: Use -mtune=generic for generic kernels
The upcomming gcc 4.2 got a new option -mtune=generic to tune
code for both common AMD and Intel CPUs. Use this option
when available for generic kernels.
On x86-64 it is used with CONFIG_GENERIC_CPU. On i386 it is
enabled with CONFIG_X86_GENERIC. It won't affect the base
line CPU support in any ways and also not the minimum supported CPU.
