Seems to be a problem of CPP varaible names in lib/ghc/IOHandle.lhs.
Try recompiling it with 
 make EXTRA_HC_OPTS="-optP-DPAR -v" ghc/IOHandle.mp_o
and check that the hscpp pass really forwards the -DPAR option.
You may have to repeat that for lib/glaExts/Foreign.lhs but the other files
should be ok --- just make the libHS_mp.a again.

HtH!
