WARNING: You don't have a mk/build.mk file.
By default a standard GHC build will be done, which uses optimisation
and builds the profiling libraries. This will take a long time, so may
not be what you want if you are developing GHC or the libraries, rather
than simply building it to use it.
For information on creating a mk/build.mk file, please see:
