Subject: [PATCH] Fix hang when locale is not UTF-8

This issue seems to have been exposed by the recent upgrade to perl-5.28.
If the system supports UTF-8 in general, but makeinfo is called using a
non-UTF-8 locale (and in this case, glibc calls it with LANG=C), then
makeinfo will get into an infinite loop and hang. We'll work around this
by removing the request for UTF-8 in the affected document.

An alternate fix would be to call makeinfo like this instead:

LANGUAGE=C.UTF-8 LC_ALL=C.UTF-8 makeinfo [...]
