It is my Request for Enhancement that the 'Configury' detect if
there is enough elf support to build gcc - in a similar manner that
gmp, mpfr, PPL and CLooG are tested for.

The configury is waiting until it gets past configuring the gcc directory,
and even detecting that gelf.h is not present, before the build fails. 

This Operating System (Debian GNU/Linux) does have "/usr/include/elf.h"
in a default installation but is 'lacking enough elf' to build without
failing. This should be checked in ../lto_trunk/configure .
