[bug-gettext] coverage reports

[Daiki Ueno]

Hello,

Just a minor heads-up: I've managed to set up 'coverage' job on the
Hydra build server, and the reports are now available online:
http://hydra.nixos.org/build/17691278/download/1/coverage/
for instance.

Although there are false-positives (e.g. the included
libcroco/libxml2/glib are used instead of system's), the results are not
very good for some modules.  So, if you write more tests that improve
the situation, please go ahead and post here or commit directly to the
master.

Thanks,
