Test failures on i386 with LLVM backend

Currently we get the following testsuite results on i386:

OVERALL SUMMARY for test run started at Fri Jan 13 22:25:17 UTC 2012
        
    3195 total tests, which gave rise to
   15839 test cases, of which
       0 caused framework failures
    3431 were skipped

   12083 expected passes
     182 had missing libraries
     132 expected failures
       1 unexpected passes
      10 unexpected failures

Unexpected passes:
   module/mod175  mod175 (normal)

Unexpected failures:
   codeGen/should_run    cgrun071 [bad stdout] (optllvm)
   dph/diophantine       dph-diophantine-copy-opt [bad exit code] (normal,threaded1,threaded2)
   driver/recomp006      recomp006 [bad stderr] (normal)
   ffi/should_run        ffi018 [bad stdout] (optllvm)
   ghc-api/apirecomp001  apirecomp001 [bad stderr] (normal)
   ghci/scripts          Defer02 [bad stdout] (ghci)
   lib/should_run        enum02 [bad stdout] (optllvm)
   numeric/should_run    arith011 [bad stdout] (optllvm)

Need to fix the LLVM failures:

   codeGen/should_run    cgrun071 [bad stdout] (optllvm)
   ffi/should_run        ffi018 [bad stdout] (optllvm)
   lib/should_run        enum02 [bad stdout] (optllvm)
   numeric/should_run    arith011 [bad stdout] (optllvm)

All seem to be incorrect results produced (no segfautls!).
