[PATCH kmod] man: silence autoconf warnings

[Emil Velikov via B4 Relay <devnull+emil.l.velikov.gmail.com@kernel.org>]

From: Emil Velikov <emil.l.velikov@gmail.com>

Currently we have a pattern rule, which effective states that two output
files are produced - %.5 and %.8. Although that's not the case in
practise, since each input xml will be generated to a single manual
page.

Add the manpage section as part of the xml filename and tweak the
pattern (match) rule, accordingly.

Noticed, while wondering if I should add sanitizer support to the
autoconf build.

A few, random questions:
 - are there any objections to adding sanitizers support?
 - would a meson.build be acceptable? Giving us sanitizers, coverage,
   scan-build, etc out of the box
 - writing xml is fiddly, would people be OK if we convert them to
   scdoc? here are some examples of the raw file [1] vs the man [2]
