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?
I think sizeof(void *).

I've told about preprocessor level method.
But thanks for your advice,
I found the way to use memcpy()!
