Subject: [PATCH] Enable compatibility with traditional man (#648854)

As of commit 46a82ade3e6f0fac8f08b18e7fc23d8665f6f728, Yelp runs
"man -Z -Tutf8 -EUTF-8 [FILE]" to obtain the groff intermediate format
of the man page. However, the only implementation of man that accepts
these options is man-db (used by Debian, Fedora, SUSE & Ubuntu).
The traditional Linux man used by other distros and man implementations
on non-Linux Unixes (FreeBSD, Solaris) do not have command-line options
for outputting groff intermediate format.
Therefore, on systems that do not use man-db, we need to manually
uncompress the nroff source file and feed it to groff. This is best done
using a small shell script (/usr/libexec/yelp-groff), both for for
clarity and for ease of modification on systems with weird man setups.
