Que?  bfdint.texi recommends this on the grounds of efficiency and the
ability to handle dynamic linking, neither of which I'm particularly
bothered about for this target.  Is there anything else I'm missing out on
by not defining the processor-specific stuff?

Say all the .linkonce.t.baz sections are combined into .text.  How is the
final link then going to know which bits to discard?  Or how would you
handle the multiple .linkonce.t.baz sections in the relocatable output?

Doh!  Why didn't I ask earlier?
