Make the configure script behave more friendly when cross-compiling.

Browse source 
It now no longer unhelpfully fails because it cannot run foreign
binaries during the configuration phase. Instead, the configuration
values necessary are read from cross.config in this case. (This just
codifies present defaults and adds sensible ones where they were still
missing). Alternative files can be specified using the
`--with-cross-compilation-info=' switch.

2012-08-25 Niels Grewe <niels.grewe@halbordnung.de>
* configure.ac: Allow a cross-compilation configuration to be
specified using the `--with-cross-compilation-info=' switch.
Tweak configure script to behave gracefully when
cross-compiling.
* configure: Regenerate.
* cross.config: Add default values for cross-compilation.
Make the configure script behave more friendly when
cross-compiling.
