    devel/glib20: fix up DOCS generation
    
    Try to resolve build issues when generating DOCS. On some systems --
    embarrassingly parallel ones, but also seemingly i386 -- the build
    happens in a wrong order. This is explained in the comment now
    added to the Makefile.
    
    A simple way to trigger the build problem (before this patch) is this:
    - configure the port
    - switch to the build-dir
    - run `ninja -j48 gio-doc`
    
    Dependencies for gio-doc are incomplete, and the build fails.
    
    I tried to solve this at Meson-level, but all my "obvious" changes
    to `meson.build` like adding a dependency on `libgdbus_example_objectmanager`
    to gio/meson.build got me Meson-time errors. Either no extra dependency
    in the resulting Ninja files, or an error that the type of the dependency
    was wrong. The ugly way to fix it is to tell ninja -- which does have
    a general idea about dependencies between targets -- about it.
