Log:
Adding support for overriding LLVM_ENABLE_RUNTIMES for runtimes builds.

Second attempt: Now with ';' -> '|' replacement.

On some platforms, certain runtimes are not supported. For runtimes builds of
those platforms it would be nice if we could disable certain runtimes (ie
libunwind on Windows).
