[PATCH] x86_64: Pass -32 to the assembler when compiling the 32bit vsyscall pages
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 2.16.91.0.2 but happens wit 2.16.91.0.5) Thanks to Brian Baker @ HP for test case and initial analysis.
