This is specific to the LLVM build, the runtimes builds do not take these parameters, and they are the primary things we’re trying to cross compile with this infrastructure.  But the monorepo makes this more complicated and makes the configure the same, so, yes, I suppose this needs to be preserved.  *sigh*


I believe the runtimes builds use the ExternalProject infrastructure. The CrossCompile infrastructure is used for e.g. building native tablegen binaries when you're cross-compiling LLVM.
