Pass -lpthread to linker when using a 'threaded' RTS

Sets the X11 C compiler and linker flags for package xlib correctly now

GhcCanonVersion: leave out GhcPatchLevel, causes problems when
the GhcPatchLevel isn't a patchlevel but a date.

* Moved CANON_HC_VERSION out of ghc/compiler/Makefile and into mk/config.mk.in
  (and renamed it as GhcCanonVersion).
* Have ghc/driver/Makefile use it; cheaper and more robust than the version
  testing it was already doing.

Change the generation of package.conf and package.conf.inplace, so that
-lbfd and -liberty are included when necessary.

back the last change out; a better way to get all the hc files you need is

	SRC_HC_OPTS += -keep-hc-files

in your build.mk.

Added $(GhcHcOpts) to $(SRC_HC_OPTS), so that by setting
--keep-hc-files-too in $(GhcHcOpts) we get .hc files for the
Haskell code under this directory, ghc/driver.

Don't install the pkgconf binary in a BIN_DIST any more.

Allow paths in package.conf to begin with the string "$libdir" which
is magically replaced by the compiler with either

  (a) the argument to the -B<dir> option, if one is present, or
  (b) the wired-in libdir otherwise.

This means that the standard package.conf file is independent of the
install location and we don't need the post-install-script hack any
more (Julian - could you update the install machinery when the time
comes? thanks.)

clean-up Main.hi

Fix a bad case of the Version Change Blues ;-)

Clean up the post-install-script mechanism a bit, so that the script
for project is <project>/mk/post-install-script.

For project ghc, don't install pkgconf unless BIN_DIST=1.

Make binary-dist installations work, by generating a proper package.conf
file.  This is done by allowing fptools packages to supply an
arbitrary post-install shell script, which the bin-dist 'make install'
runs last of all.  In Project=Ghc's case, the post-install script
runs pkgconf with appropriate params to create the package.conf
file in the right place.

Install ghc-usage.txt, too

Install package.conf in the right place.

- make the pkgconf program independent of the location of the build
  tree - instead of Config.hs, we pass the configuration parameters in
  as options.  This is necessary for .hc bootstrapping.

- remove the ghci driver stuff, it moved to the ghci subdirectory.

- remove ghc5.hs

Basic support for the simplified installation story.

- Don't duplicate the definition of PackageConfig, instead hackily #include
  it from ../utils/ghc-pkg/Package.hs.

- Add missing source_dir fields to PackageSrc.hs.

make ghci-inplace work

Remove some duplicate Makefile gunk, and collect the symbolic link
code together in mk/target.mk.

clean up a little

Create ghci-$(ProjectVersion) and ghci-inplace mini-scripts, and a
ghci->ghci-$(ProjectVersion) link.

I put these in here rather than ghc/compiler, because ghc/compiler
already has a ghci subdirectory.

Remove now-unused stats script.

Put back accidentally butchered Config.hs

remove old driver.

merge recent changes from before-ghci-branch onto the HEAD

merge rev. 1.44.2.4

merge before-ghci -> before-ghci-branch-merged into the ghc
(non-compiler) parts of the tree.

Rename the make variable TMPDIR to DEFAULT_TMPDIR.  This fixes the
problem that saying 'TMPDIR=/foo make' in an fptools tree didn't work,
because GNU make is in the habit of overriding an environment variable
with the value of the corresponding make variable in a sub-process.

Assimilate mkdependHS into the driver, obsoleting the old Perl version.

The functionality is pretty much identical, except a few of the flags
accepted by the old version aren't implemented (--exclude-module,
--exclude-directory, --include-module).  If anyone needs these
options, please speak up.

Windows fixes.

ghc 4.06 didn't have -package, so use it only for 4.07+.

wibble

Use GhcMinVersion to pick the correct cmdline args to build the driver.

Wave goodbye to hscpp, GHC's lexer now understands the '# \d+ \".*\"'
output from cpp.

Changed "_" variable prefix to "c" (for "config", "constant", or
whatever you like). This should enable building from CVS with GHC <4.07.

Use "$@" instead of $* in shell script, the latter one doesn't handle
spaces in arguments correctly. Heaven knows who invented this wierd rules.

don't use $(WithGhcHc) to build the driver, use $(HC) instead.

move "boot :: all" after target.mk, so we make dependencies in the
current directory before going on to build the driver.  This still
doesn't really work because GNU make doesn't re-load the .depend file,
but it's heading in the right direction.

also, clean ghc-inplace and ghc.
