- Move FptoolsHcOpts out of the hslibs section of this file (which was
  *exactly* the wrong place for it).

- Clarify the meaning of FptoolsHcOpts and GhcHcOpts.

NOTE: $(FptoolsHcOpts) gets added to every Haskell compilation for
Haskell *programs* (not libraries), including GHC itself.  By default,
it contains only -O.  To remove the -O, you need to override
FptoolsHcOpts in build.mk, not GhcHcOpts.

GhcHcOpts is still there, and contains options to be added when
compiling GHC only.
