This could probably be done.  In gld${EMULATION_NAME}_place_orphan()
in ld/emultempl/elf32.em copy any AT statement into the call to
lang_leave_output_section_statement().  You will need to properly
adjust it for the size of the section which you are following.  This
will be ld expression hackery--shouldn't be too tough.

That too is in gld${EMULATION_NAME}_place_orphan().  Search for
__start.
