source: configure @ f60079b

Last change on this file since f60079b was f60079b, checked in by Wilmer van der Gaast <wilmer@…>, at 2010-05-25T22:26:54Z
Allow one to run the configure script from a different directory and put all build files in there. I need this to properly make Debian package variants (i.e. libpurple and native).
