Segmentation fault during build of 5.04.3

That gives me an idea: try recompiling genprimopcode with -fasm and see
if that solves the crashes:

  cd ghc/utils/genprimopcode
  make clean
  make EXTRA_HC_OPTS=-fasm

These are harmless: GHC is fully aware of the dangers of borrowing
call-clobbered registers, but gcc doesn't know that :-)
