    gdb/doc: fix install-html with Texinfo 7
    
    Starting with Texinfo 7 (this commit [1]), the output directory for the
    HTML doc format is gdb/doc/gdb_html, rather than gdb/doc/gdb previously.
    This breaks the install-html target, which expects the HTML doc to be in
    gdb/doc/gdb:
    
        $ make install-html MAKEINFO=makeinfo DESTDIR=/tmp/install

    Fix this by adding -o switches to the HTML targets, to force the output
    directories.
