I think we're slowly setting on llvmcs (LLVM Compiler Suite or
Compilation System).

I tend to agree. I'm a strong advocate of XML myself (on other
projects). However, introducing XML would make LLVM dependent on some
kind of XML parser. We could probably get away with expat (small, fast)
for our purposes in LLVM, but there is still the issue of dependency. To
avoid dependency, its possible a simple, recursive descent parser that
only understood the LLVM configuration document type could be written.
Perhaps others could chime in on this issue. Is the need to keep LLVM
independent of other packages that strong? We already depend on GCC and
several other tools (bison, flex, doxygen, unix editors, etc.) Is one
more  a big deal?
