Translations not made in file tests at distcheck

[Gavin Smith]

When I run "make distcheck", there are two test failures:

FAIL: t/init_files_tests.t 44 - customize_translations converted file_html
FAIL: t/init_files_tests.t 66 - customize_special_element converted file_html

These tests pass usually when I just run "make check".

I found that the files were not translated properly:

I suspect that the translation files are not being found in out-of-source
builds.  This is a new problem.
