Make sure we depend on the right name of mkdoc all the time, and that
the rules that need it (e.g. .def files) depend on it.

This allows building the libc & libm pages in parallel, and drops
the duplication in the subdirs with the chew/chapter settings.
The unused rules in Makefile.shared are left in place to minimize
noise in the change.
Teach makedocbook how to handle some new things seen in the makedoc markup
since eae68bfc:
- 'link with' lines appearing in SYNOPSIS sections
Also, don't raise a NoneType exception when there's something we don't
know how to handle in a SYNOPSIS section, just exit.

Subject: [PATCH] nvptx port
This port adds support for Nvidia GPU's, which are primarily used as
offload accelerators in OpenACC and OpenMP.
To follow up the thread starting at [1], since all uses of TRAD_SYNOPSIS
have been removed, and all uses of ANSI_SYNOPSIS have been renamed to
SYNOPSIS, we can now warn about the use of these.

Add makedocbook, a tool to process makedoc markup and output DocBook XML
refentries.
Process all the source files which are processed with makedoc with
makedocbook as well
Add chapter-texi2docbook, a tool to automatically generate DocBook XML
chapter files from the chapter .texi files. For generating man pages all we
care about is the content of the refentries, so all this needs to do is
convert the @include of the makedoc generated .def files to xi:include of
the makedocbook generated .xml files.
Add skeleton Docbook XML book files, lib[cm].in.xml which include these
generated chapters, which in turn include the generated files containing
refentries, which is processed with xsltproc to generate the lib[cm].xml
Add new make targets to generate and install man pages from lib[cm].xml

Align makedoc's iscommand() with it's documentation, and don't allow commands to
contain a space. A command is a line containing only a sequence of capital
letters or '_', followed by optional spaces.
This prevents "IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A
PARTICULAR PURPOSE" (the only line in the license text which consists of only
capitals and spaces, without any punctuation) from being interepreted as a
makedoc command, leading to:
"Can't find IMPLIED"
"warning, IMPLIED is not recognised"
being emitted by makedoc, (which is normally un-noticed because makedoc's stderr
is redirected to a .ref file)

The unused INTERNAL_DEFINITION, INTERNAL_FUNCTION and INTERNAL commands are
defined in terms of the non-existent built-in 'func'
This causes every single invocation of makedoc to output "Can't find func" three
times, as it parses doc.str.
This is normally un-noticed because makedoc's stderr is redirected to a .ref
file.
Fix these unused command definitions to something with equivalent lack of
effect, but without generating an error.

So it seems this problem has been around for a while, and looks like it
is due to a change in texi2dvi in texinfo 5.0 or late 4.x, see [1].
I guess it's not very noticeable since it only occurs when doing 'make
dvi', which doesn't happen by default.
Attached is a different and perhaps cleaner workaround to the one in
that thread.

Subject: [PATCH] Use '@sp 1' rather than '@*' to workaround a change in

Since about TexInfo 5.0, using '@*' immediately after a table causes a 'You
