I have similar requirement for Ravi when compiling AOT.
I think though that vast majority of scenarios will be covered by
clang, gcc, and MSVC.
And typically all I need is to compile a single C source to
corresponding dynamic library.

I think it can be a simple Lua script that know the options for the
commonly used C compilers; I would suggest avoiding heavyweight
solutions that are being proposed. I am not aware of an existing
solution though.
