Unfortunately I didn't have much time after the OpenBSD p2k9 in
Budapesst (where I got a little bit further with the bootstrapping),
but I remember that I got parts of stage 1 built but then something
in utils/* didn't compile.

I hope to have a look this weekend (and to find the patches I wrote
in Budapest). There are probably just some more pattern rules missing
for the .hc file bootstrapping.

Once the make rules are complete, the Linker may be tricky (it
already contains #ifdef'd sections specific to FreeBSD and OpenBSD),
but I don't expect other parts of GHC to need tweaking.

At least I tried to correct some of the hints on the porting wiki
page, but it's obviously still incomplete.
