This changes adds support for building runtimes for multiple different targets using LLVM runtimes directory.

The implementation follow the model used already by the builtins build which already supports this option. To specify the runtimes targets to be built, use the LLVM_RUNTIME_TARGETS variable, where the valuae is the list of targets to build runtimes for. To pass a per target variable to the runtimes build, you can set RUNTIMES_<target>_<variable> where <variable> will be passed to the runtimes build for <target>.
