This is something we'd like to do, but haven't got around to. It's not
just a case of adding the correct flags to gcc/ld unfortunately: GHC's
assembly mangler needs to be taught how to generate the unique section
names for each function. But then it's possible that we could remove
the grotty -split-objs stuff that we use to split the libraries into
small pieces.
