[PATCH] gdbserver: Add .dir-locals.el file

[Andrew Burgess <andrew dot burgess at embecosm dot com>]

Add a .dir-locals.el file into the gdbserver directory so that we get
the GNU style when editing these files in Emacs.

I copied this file over from the gdb/ directory and the only change I
made was to remove (mode . c++) from the c-mode settings.  The reason
for this is that all C++ files in the gdbserver/ directory now have
the .cc suffix, and we don't (currently) have any .c files in there. I
assume that if did add a .c file in the future, it really would be C,
not C++, so forcing c++-mode seems like the wrong thing to do.

The copyright date in the new file is left as for gdb/.dir-locals.el,
as the new file is an exact copy with one line removed.
