This is no substantial change, as we already assert that the build->target and host->target LLVM are the same, but this brings the terminology in the file in a more consistent order, since we use build->target for CC/CXX and bintools already. In fact we should be passing build->target to configure always, host->target would come into play when updating GHC's settings file after installing.
