Why? You've introduced yourself as a Linux- and Ada-newbie.

It's clearly mentioned on the website. Ok, nowadays it's no longer
necessary to specify it, because libada (gnatlib_and_tools) would
be built by default.

   --enable-__cxa_atexit
          Define if you want to use __cxa_atexit, rather than atexit, to
          register C++ destructors for local statics and global objects.
          This is essential for fully standards-compliant handling of
          destructors, but requires __cxa_atexit in libc. This option is
          currently only available on systems with GNU libc. When
          enabled, this will cause -fuse-cxa-exit to be passed by
          default.

You're making a compiler in a multi-stage-way. Every stage can do
more than a lower one. The last stage contains your full-featured
compiler.

Perhaps you might be interested in binary-Ada-packages or the
Debian unstable-distribution. A lot of other nice packages are
available for it making first steps with Ada much easier.
