 In mk/build.mk, you specify the build flavor you want for the compiler.
 Often during development, a good default is 'quick'. But sometimes I also
 want to be able to do a quick build using the LLVM backend.

 This is in line with other build modes, such as perf/perf-llvm.

 I have a patch for this that I will offer up shortly.
