Agreed.  That's why it took me so long to recognize what was happening. 
 I wasn't looking for this possibility.  Is there another explanation 
that the software builds after eliminating /usr/lib/libgcc*.a ?

So in this case -static-libgcc doesn't help because both packages where 
I encounter this, the static libgcc was being used already (the wrong 
one).  The other methods will probably work, but they'll have to be 
applied every time gcc is used.  In other words, it wouldn't be an 
occasional override, but one to be applied always.  Ideally gcc should 
be configured to work as expected without special overrides.
