I ran into very similar problems on ubuntu 11.4. The culprit seems to be 
binutils version 2.21.something. (I think the assembler is suddenly more 
strict in some situations and aborts assembling with these error messages.)

There is a related bug report in ghc's trac: [1]. According to that, you 
could try to remove the "-fvia-C" flag to prevent ghc from using the C 
backend. (I had no luck with that, so I guess there is still another bug
