source: configure @ 2e78f75

Last change on this file since 2e78f75 was 2e78f75, checked in by Jelmer Vernooĳ <jelmer@…>, at 2016-05-15T17:16:38Z

Remove the ARCH / CPU defines.

These only reflect on what arch/cpu bitlbee was built, not on which
it is running. This makes the Debian package unreproducible.
See e.g.
https://tests.reproducible-builds.org/rb-pkg/testing/i386/bitlbee.html

Property mode set to 100755
