Is there another trick I don't know yet? E.g. can I create section-aliasses or something like that? (again, a short google session didn't give useful results)

Yes, for those sections you do need to use a linker script, or to
arrange for some file defining the appropriate symbols to be at the
start and end of your link.

For specialized purposes like this you do need to use a linker script
with gold.  gold is optimized to not use a linker script for the
ordinary case of a hosted system.  It's OK to use a linker script for
an embedded system.
