I'm not working on this, though I am interested in helping enable
cross-compilation of GHC in general. I have been working on one facet
though: hsc2hs. hsc2hs is one of barriers to cross-compilation because
it requires compiling and running a .c file on the target machine
(because it needs target-specific information like the layout of
structures; GHC's mkDerivedConstants also has the same problem).

I have a proof-of-concept patch which can do hsc2hs codegeneration
without running anything. This uses the same approach that autoconf
uses for cross-compilation. I'll try to post it within the next few
days -- if anybody finds this approach interesting please let me know.
