 It is a bit tedious right now have to track GhcLibWays, etc by hand to
 turn off building of prof libs, etc.  It would be nice to have a simple
 configure option just to turn off profiling (eg --without-profiling) to do
 this.

 Things might be slightly better with 6.11 but I think it probably applies
 there too.
