actually, as of current trunk (likely 167292) the spec-processing for  
suffixes appears to be fixed (good timing eh?).

we know that dsymutil produces a number of (stated by the dsymutil  
maintainers to be spurious & harmless) warnings.
These will cause Fortran test-suite regressions unless handled
    (I produced a wrapper script to filter them, if you recall -  
attached to comment #4 of PR43751)
    or we could put 'prune' statements in the relevant tests.

Although the script is a hack, it does have the advantage that it is  
one point of fixing rather than many - and that it can be easily  
removed if/when the dsymutil problems are resolved.

Anyway, that's for a different patch/thread  - this issue has 'gone  
away' ...
