doc: Specify the CWD explicitly for gdb-cfg.texi

[Maciej W. Rozycki]

Hello,

 Contrary to documented behaviour `texi2html' does not search the current 
directory for include files.  I get:

*** Can't find gdb-cfg.texi, skipping at /usr/bin/texi2html line 3662, <FH001> line 11.

with version 1.66 and:

*** Can't find gdb-cfg.texi, skipping (l. 11)

with version 1.76.  That deserves a bug report against `texi2html', but 
the following trivial workaround makes `make html' work as expected with 
versions already in existence.

gdb/:
2007-07-25  Maciej W. Rozycki  <macro@mips.com>

	* Makefile.in (MAKEHTMLFLAGS): Also search the current directory
	for include files.

gdb/doc/:
2007-07-25  Maciej W. Rozycki  <macro@mips.com>

	* Makefile.in (MAKEHTMLFLAGS): Also search the current directory
	for include files.

 OK to apply?

  Maciej
