Guenter Roeck reported problem with compilation when the ARCH is
specified:
$ make ARCH=x86_64
In file included from tools/include/asm/atomic.h:6:0,
from include/linux/atomic.h:5,
from tools/include/linux/refcount.h:41,
from cpumap.c:4: tools/include/asm/../../arch/x86/include/asm/atomic.h:11:10:
fatal error: asm/cmpxchg.h: No such file or directory
The problem is that we don't use SRCARCH (the sanitized ARCH version)
and we don't get the proper include path.
