Invocation mismatch - some data files may have been removed

[Jack Howarth]

   I am seeing some non-fatal warnings when doing a 
profiledbootstrap/ltobootstap on
x86_64 darwin. These are of the form...

profiling:/sw/src/fink.build/gcc47-4.7.0-1000/darwin_objdir/gcc/graphite-poly.gcda:Invocation
 mismatch - some data files may have been 
removedprofiling:/sw/src/fink.build/gcc47-4.7.0-1000/darwin_objdir/gcc/omega.gcda:Invocation
 mismatch - some data files may have been removed

are these expected?
