glibc 2.12.1 will not compile on Ubuntu 10.10

["J. Random Coder" <jrandomcoder at gmail dot com>]

I have a fresh installation of Ubuntu 10.10. (GCC 4.5.1, binutils
2.20.51.20100908-0ubuntu2). Glibc will not compile, choosing instead
to puke out the following errors:

---------

---------

Googling these error messages, I find that most hits seem to be
referring to this problem as being something caused by cross
compiling; however, I am NOT cross compiling at all. I simply run
../configure --prefix=/ from my build dir, then go 'make', and this
happens. Bam.

Again, I am trying to compile glibc for i686 on i686. This is not a
cross-compiling situation at all.

Any information anyone could provide towards helping me resolve this
problem would be very much appreciated.
