Matthew Bauer ead13a3aca llvm: don’t use targetPlatform
LLVM should be target independent because it will work with all
machine types. This is different from GCC where it needs to know what
target to build ahead of time.

# get no binary cache for the entire platform. If you really find yourself wanting the TSAN, make this controllable by
