Change the way the top-level Makefile works, now that we have a dependency between ghc and hslibs which means that you can't `make boot' in hslibs until you've done `make all' in ghc. - now you just type `make all' at the top-level, and the makefile arranges to do `make boot all' in each of the subdirectories. Typing `make boot' at the top-level now yields a message explaining what's going on. - Now it's no longer necessary to set $(ProjectsToBuild). If you don't set it, the build system attempts to build all the projects in the source tree, in the order determined by $(AllProjects) in config.mk. I've been meaning to fix this for ages, since it meant that one had to hand-edit config.mk.in when making a distribution for anything other than GHC - this is no longer the case. You still *can* set ProjectsToBuild if you want to, however. - ProjectsToInstall has been replaced by ProjectsDontInstall, and has the obvious, reverse, meaning. It also has a reasonable default, so the need to set it should be rare. All this has the obvious benefit that to build GHC you need one fewer commands (no more `make boot'), and anyone that has "./configure && make && make install" hardwired into their brains will feel right at home.
