LCC: Support for MCST LCC compiler
Opened as a disussion for MR !6579 (merged) as @brad.king suggested:
Please open an issue to track progress on support for this compiler.
Follow-up of discussion regarding support of LCC compiler, and, probably, other EDG-based compilers should go here.
LCC is the only production compiler for Russian Elbrus (E2K for short) CPU (although there is experimental Clang/LLVM exists), so it'd be nice if CMake will be buildable and working with this compiler out-of-the-box.
