Test failures on Debian 9: indic-old-spec, kern-format2, use-syllable #1560
Description
Hi,
I'm trying to backport 2.3.0 from Debian unstable/testing to Debian stable (Debian 9 aka. Stretch), and while the build itself seems fine, there are test failures.
Quoting the relevant parts (from test/shaping/data/in-house/test-suite.log, hoping it's OK; attaching it wouldn't help search its contents, I suppose):

I'm attaching the buildinfo file obtained from a “successful” build (i.e. ignoring test failures), which contains the list of installed build-dependencies, in case their versions help you spot something fishy.
