Binary distributions produced from cross-compiled stage2 are broken

The binary distribution by a cross-compiled build (e.g. configure with ./configure --target=$cross_target) is broken out of the box.

After untarring and configuring the bindist, make install fails due to missing files,

# make install
make --no-print-directory -f ghc.mk install BINDIST=YES NO_INCLUDE_DEPS=YES
ghc.mk:742: utils/ghctags/ghc.mk: No such file or directory
ghc.mk:742: utils/check-api-annotations/ghc.mk: No such file or directory
ghc.mk:742: utils/check-ppr/ghc.mk: No such file or directory
make[1]: *** No rule to make target 'utils/check-ppr/ghc.mk'.  Stop.
Makefile:51: recipe for target 'install' failed
make: *** [install] Error 2

This can be worked around by,

$ mkdir utils/ghctags utils/check-ppr utils/check-api-annotations
$ touch utils/hp2ps/dist/build/tmp/hp2ps \
        utils/ghctags/ghc.mk \
        utils/check-api-annotations/ghc.mk \
        utils/check-ppr/ghc.mk

I believe the reason for this is that these are utilities which would typically be built by the stage2 compiler, which we obviously are unable to build.

There are a few options for fixing this,

• Produce a shell script throwing an error to sit in place of the unbuildable utilities
• Fix the build system to include the appropriate ghc.mk files in the bindist, despite the utilities they build not being present
• Include the sources for the utilities in the bindist and teach make install to build them
