[fink-core] issues with path-prefix

[Benjamin R. <ra...@be...>]

I get the following when building Qt:

---(snip!)---

The symbols ___gcc_qadd and friends are coming from a .o file that was 
c, not c++, and thus was generated with gcc4.  Those symbols exist only 
4.0's libgcc, not in 3.3's.

It looks like the path-prefix stuff will need to override gcc, not just 
g++ or we need to figure out how to keep such 4.0-only symbols from 
sneaking in.
