install-html and install-pdf improvements

["Joseph S. Myers" <joseph@codesourcery.com>]

This patch improves "make install-html" and "make install-pdf" support
for GDB:

* There are toplevel configure options --with-htmldir and
  --with-pdfdir to control where HTML and PDF manuals are installed.
  This patch makes the gdb/ directory follow these rather than
  hardcoding its own directory settings.

* The readline and sim directories need some dummy rules so that these
  targets work at toplevel.

Note: with the version of texi2html I have installed "make
install-html" doesn't actually work either before or after the patch,
because gdb/doc/Makefile.in is expecting files such as gdb_toc.html to
be placed in the current directory and texi2html is placing them in a
gdb/ subdirectory.  I have a separate patch to switch to using
makeinfo --html, which is more predictable in its output naming and is
the usual approach used by GNU software for building HTML manuals, but
that's logically independent of this patch.

OK to commit?
