Yeah, I just realized how to fix it.

Changing the "Global command prefix" from (BLANK) to i386-elf in the 
configtool makes it work fine.  This causes the compiler to use the gcc used 
for the i386-pc target, which works fine for the synthetic linux target.

I apologize for writing the list.  Seems everytime I do, I figure it out 5 
minutes late.

Furthermore, this should have been obvious since GCC 3.0 has changed so 
radically since 2.95.  The __gnu_cxx namespace, for example...
