Odd build errors

[Jeff Blaine]

We have a GCC in /usr/rcf that was not built with --disable-shared.
As such, there is a /usr/rcf/lib/libgcc_s.so.

We also have a (preferred) GCC in /afs/rcf/lang/gcc/current that
was built with --disable-shared. As such, there is no
/afs/rcf/lang/gcc/current/lib/libgcc_s.so and binaries built
with this compiler do not link to any shared libgcc_s.

I have the following problem with Python 2.4.2. I also tried
2.4.4. Moving up to 2.5 is not an option.

Problem: Builds fine! Rebuild after dropping in Setup.local
causes some magic new build process that ends up
finding and linking in /usr/rcf/lib/libgcc_s.so !
