I added those three lines to the file (just in yesterday's linux-next
was easiest) and got this:

/home/sfr/next/next/tools/include/asm-generic/bitsperlong.h:14:9: note: #pragma message: BITS_PER_LONG=(8 * 8)
 #pragma message "BITS_PER_LONG=" __stringify(BITS_PER_LONG)
         ^
/home/sfr/next/next/tools/include/asm-generic/bitsperlong.h:15:9: note: #pragma message: __BITS_PER_LONG=32
 #pragma message "__BITS_PER_LONG=" __stringify(__BITS_PER_LONG)
         ^

(a few times, of course)
