 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
