Locating library modules during link

Err, why doesn't something like this work:

        SECTIONS
        {
                .libtext : { *(.libtext) }
                .libdata : { *(.libdata) }
                .text    : { *(.text) }
                .data    : { *(.data) }
        }

This should place the .libdata section contents next to the .libtext
section contents, and assuming that you start .libtext at the start of
fast RAM, you should get the best placement possible.
