Memory consumption should not be massively affected by the underlying processor architecture so you might be able to do the memory profiling on x86 Linux. Yes, the absolute amounts of memory probably are a affected but as you're looking more for relative than absolute numbers, this should work.

That said, this solution is unlikely to be an option if a Linux x86 build is more than a recompile away.
