[llvm-dev] Use of host/target compiler when building compiler-rt

[Evgenii Stepanov via llvm-dev]

FTR, I've tested compiler-rt in runtimes/ directory.

There is a missing dependency of check-runtimes on test tools (FileCheck, not)

There is no top level check-asan target (as promised in the August
thread), even after runtimes-configure. There is one in the ninja file
under runtimes/runtimes-bins. Is that a regression?
