Bugzilla Bug 68700

emerge -C gcc-config && emerge gcc-config gives unexpected results.

gcc-config will contain only 'wrapper' and 'gcc-config' programs. so perhaps gcc-config itself shouldn't depend on system gcc-config, but rather use (or fallback) to own sources.

Reproducible: Always
Steps to Reproduce:
1. emerge -C gcc-config
2. emerge gcc-config

-rwxr-xr-x  1 root root 7.4K Oct 24 16:22 /usr/lib/gcc-config/wrapper*

Actual Results:  
 

Expected Results:  
gcc-config package to contain all those cpp,gcc,g++ wrappers

1.3.7-r1 now adds $S to first PATH element so it'll use the new packaged
gcc-config instead of anything else
