--enable-cxx is the culprit of the abort above.

You are explicitly demanding the configure script to use C++, which 
fails for the avr, because the avr does not support C++.

Omit this option from the configure-call and your configuration should 
finish without problems.

This is a misunderstanding. The RTEMS toolchains for CentOS 4 were 
discontinued, because this distribution's vendor has discontinued it.

CentOS 5 and CentOS 6 are well alive and so are the corresponding RTEMS 
toolchain packages.
