[RFA] do not try large-files support by default on 32bit sparc-solaris

[Joel Brobecker]

> That should only be done in a native configuration.

Yes, you're right. Here is a new version of the patch that only does
that for native configuration.

2008-11-13  Joel Brobecker  <brobecker@adacore.com>

        * configure.in: Deactivate large-file support on native 32bit
        sparc-solaris unless the user explicitly requested it.
        * configure: Regenerate.

Tested by rebuild on sparc-solaris. I tried with and without
--enable-large file. In the latter case, the build failed, as expected,
showing that large file support has been included to the detriment of
some elf routines.
