Makefile.am (building docs): create target directory before writing into it.

To reproduce build falure (before the fix):

    $ mkdir <builddir>
    $ cd <builddir>
    $ ../condigure --disable-dependency-tracking
    $ make src/conf/help.cc V=1
    cp ../bootstrap/src/conf/help.cc src/conf/help.cc
    cp: cannot create regular file ‘src/conf/help.cc’: No such file or directory
    Makefile:1984: recipe for target 'src/conf/help.cc' failed
    make: *** [src/conf/help.cc] Error 1
