Subject[patch 04/24] x86_64: Pass -32 to the assembler when compiling the 32bit vsyscall pages
-stable review patch.  If anyone has any objections, please let us know.

This quietens warnings and actually fixes a bug. The unwind tables would
come out wrong without -32, causing pthread cancellation during them
to crash in the gcc runtime.

The problem seems to only happen with newer binutils
(it doesn't happen with but happens wit

Thanks to Brian Baker @ HP for test case and initial analysis.
