I added those three lines to the file (just in yesterday's linux-next was easiest) and got this:
quoted
/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)
quoted
/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)
quoted
(a few times, of course)
So I applied this:
quoted hunk ↗ jump to hunk
+++ b/tools/arch/x86/include/uapi/asm/bitsperlong.h@@ -4,6 +4,12 @@ #if defined(__x86_64__) && !defined(__ILP32__) # define __BITS_PER_LONG 64 #else +#ifndef __x86_64__ +#pragma message "__x86_64__ is not defined" +#endif +#ifdef __ILP32__ +#pragma message "__ILP32__ is defined" +#endif # define __BITS_PER_LONG 32 #endif
and got this:

Humm, it seems that the compiler used is not the cross one, but the native, check if, say, __powerpc__ is defined. - Arnaldo
