If you're modifying LLVM, then I'd strongly recommend that you use CMake+Ninja.  On a moderately fast machine, it takes less time for me to do an incremental build with ninja after modifying a few files in the MIPS back end than it takes to do an incremental build with the autoconf / make system after modifying no files.
