This looks like a mangler or a splitter problem (those manky Perl
scripts we use to postprocess assembly code).  Probably gcc 3.4.3 is
generating something we don't recognise.

Could you try the following:

  - Add SplitObjs=NO to build.mk, recompile the libraries (make clean
    && make) and try to compile a simple program with the stage1 ghc.
    If that works, then it's a splitter problem.

  - If you get link errors, then
 
     $ cd libraries/base
     $ rm -f GHC/Base.o
     $ make GHC/Base.o EXTRA_HC_OPTS='-keep-s-file -keep-raw-s-file'
  
   and send me the contents of GHC/Base.s and GHC/Base.raw_s.
