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- ProjectsToInstall has been replaced by ProjectsDontInstall, and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.
