This is minimal patch that add basic cross-compilation possibilities for
python build (configure script).
The patch add macro AC_CANONICAL_HOST.
This macro require files config.guess, config.sub. The patch don't
include them. You may obtain them from GNU automake tarbal.
As result of macro new variable $host ("host triplet":=cpu-verdor-os) is
used to detect so called "host system".
Since this is basic patch, detection of build system in native builds
based on $ac_sys_system and/or $ac_sys_release isn't replaced. This
detection isn't appropriate for cross-compilation environment as contain
values for "build system" and has to be replaces in addition by future
patches.
Also the patch posted in http://bugs.python.org/issue3718 (about
environment variable MACHDEP) isn't required for native builds, but will
help in case of cross-compilation.
