I got linker errors, since /lib/clang/3.5/linux/libclang_rt.asan-armv7l.a
(or arm for that matter) wasn't there, since "arm" is not a recognized

My point is that Clang sanitizer tests should *only* run IFF:

1. Compiler-rt is present AND
2. The architecture is recognized AND
3. The Asan/Lsan/UBsan etc libraries were enabled via some build option
(individually checked).

I may be wrong, but right now, it seems that they all run once compiler-rt
is available.
