- gettext requires recent autotools
- add for Ubuntu 14.04 (trusty) - fixes#1892
- add deps for Debian Jessie and Wheezy
- libtool is built for prior Debian/Ubuntu, remove from docs
- tidy up darwin overrides
fixes#1934
The method of symlinks to native tools fails when glib versions drift
too far apart - the obvious solution would be to update more frequently,
but glib (and downstream friends) are always difficult to update.
This set of changes:
- always builds tools on linux
- builds tools only once
- uses pre-built packages for darwin
- is untested on freebsd
