I have had the same problem. What I found was that the glibc configure
script was testing for a version of gcc 3.2.* or later. It does not test
for a major number above 3 so the test fails. I do not know where this
test is initiated, but once you have reached that point you can patch
the configure script and run demo-*.sh with the --nounpack option added
to your desired toolchain build. 

This patch worked for me:

--- configure.orig      2005-09-19 21:31:45.000000000 -0400
+++ configure   2005-09-19 21:32:13.000000000 -0400

   esac

I hope that this helps. Good Luck.
