I managed to build 6.12.3 with the aid of .hc files. The problem now is
that rts/StgCRun.c:95 (StgRun), called from  rts/Schedule.c:484
(schedule) use the function: stg_enter_info , which only seems to be
available for a registered build, not an unregistered, which is required
when cross-building.

Thanks, I will try cross-compiling next (if everything else fails) not
cross-building.

BTW: The mail subject should have been cross-build, not cross-compile.
