.../tools/include/asm-generic/bitsperlong.h:8:0: error: "BITS_PER_LONG"
redefined [-Werror]
#define BITS_PER_LONG (__CHAR_BIT__ * __SIZEOF_LONG__)
Include <asm/bitsperlong.h> instead as other headers do.

Seen during x86_64 build. Seems that most of the compilers do not define
__SIZEOF_LONG__, but my does.
