This change enables building builtins for multiple different targets using LLVM runtimes directory. To specify the builtin targets to be built, use the LLVM_BUILTIN_TARGETS variable, where the value is the list of targets. To pass a per target variable to the builtin build, you can set BUILTINS_<target>_<variable> where <variable> will be passed to the builtin build for <target>.
