[v4,4/5] Include group information in xml syscall files.

  We maintain linux-defaults.xml.in, a template file to hold generic group
information.  It is used by the XSL script that parses the architecture
specific files to generate the final xml files, which are actually
installed and loaded by GDB.  The script is not run during the build
process, and must be run manually by a GDB maintainer when there is need
to update the syscalls information files.

Hi.
I would have expected syscalls/Makefile.in,
with requisite changes to generate Makefile in some configure.ac file.

Hi Doug,

I saw your other message and I'll surely answer and apply your
suggestions as soon as I can, but let me make a quick question and
comment on my design here :)

I tried to follow the exact same design we have in gdb/Features.  There,
we only have a Makefile that doesn't depend on the configure script.  If
I understand correctly, all it takes to generate the files is a simple
'make blah'.  I tried to reproduce this behavior here.

Even though I understand the obvious benefits of using the configure
script, is there any actual differences between the expected behavior in
gdb/Features/Makefile that justifies it being a simple Makefile?  If
not, I'll probably work on a follow-up patch adjusting it, as well.

Btw, can any of you guys provide me with more information about the
maintainers mode?  I couldn't find many explanations in the Internals
wiki.  I can update the wiki once I have a better understanding of
it.
