The *first* GCC works to build glibc.  The problem is with the second one, 
with shared libraries and C++ support (and separate libgcc_eh, which is 
what actually results in the undefined references), since you want to 
rebuild with such a second compiler before running the testsuite (the 
expectation is that a bootstrap compiler will produce a correct glibc, but 
not a build tree suitable for testing in).
