this header file includes autoconf.h which is generated

This makes building of perf depend on building of kernel.
It's a little dirty. But perf has tight relation
of its kernel, so I don't think that it is a serious problem.
My original purpose of making this patch is
knowing size of void *.
If config.h is available,
CONFIG_ARCH_PHYS_ADDR_T_64BIT will be provided for source of perf,
we can know size of void * by this config.
How do you think?
directory (e.g., using "make O=../builddir vmlinux")? I think that
trying to include generated files will fail in that case.
In general I think that tying perf to the kernel config is a bad idea.
