[LLVMdev] non-x86 sanitizer buildbots: no rule to make target check-lsan etc.

[Jay Foad]

How about tweaking the compiler-rt cmakefiles so that if lsan is not
supported, the target check-lsan still exists but does nothing? I've
attached a patch that does this. (I don't know much about cmake so
there might be a better way of doing it.)

Alternatively, can I change the zorg build script so that "run
sanitizer tests in gcc build" doesn't try to run check-lsan etc unless
we're on x86-64? I've attached a patch for this too.

I can submit either of these patches via phabricator if you'd prefer.

Thanks,
Jay.
