You should not IMHO. My patch should solve all your issues. :-) The only 
issue you may get is that your distro ghc will compile for soft-float 
ABI and your compiled GHC will compile to hard-float and object files 
will get mixed somewhere. But I trust your distro ghc builders that this 
is not the case so both GHCs should compile using hard-float. So issue 
solved, at least should be. Now I'm just waiting if you verify this or 
not so I'm either able to submit the patch for inclusion or hack it more...
