[CMake] Support Macros in Linux

Browse Source 
For compiling codes required for macro support, we now need swiftc
compiler in the build machine.

Unlike Darwin OSes, where swiftCore runtime is guaranteed to be present
in /usr/lib, Linux doesn't have ABI stability and the stdlib of the
build machine is not at the specific location. So the built compiler
cannot relies on the shared object in the toolchain.
