Removed info and texinfo support.

Replaced SGML2INFO stuff (which is no longer supported) with SGML2PS (which
is, and may well be useful to some).

Added SplitObjs for when -split-objs is being used. Removed -split-objs and
-odir from GhcLibHcOpts. -odir shouldn't be needed any more in any case.

Changed order of recursive makes so that recursive make happens before make
in the current directory. This helps when building hslibs as DLLs, where
the cbits DLLs need to be made before the main DLLs.

Changed rules to make SGML documentation using DocBook tools rather than
LinuxDoc.

DLL install support

Added support for dllwrap options

- define and use *_OPTS for the various sgmltools.
- acknowledge the existence of INSTALL_LIB_SCRIPTS.

AT_GLASGOW went away.

Added ZIP_OPTS

Renamed SRC_HC_{PRE,POST} to HC_{POST,PRE}_OPTS

New option variables: HC_PRE and HC_POST; $(SHELL) actions to perform before & after compiling a Haskell source file

Suppressing the generation of a default rule (-s) is a local property of a flex spec, not global

Added suffix rules, option variables, etc for greencard

Added INSTALL_BIN_OPTS plus default is to strip installed binaries

Major update to more-or-less 2.02
