I did a quick scan and the ones with r_addend != 0 all seem to be
references to .text from the .init.text, .exit.text or .fixup
sections.  Assuming we can get those allocated near each other they
shouldn't need trampolines.

Rusty, do we manage to put .init.text and .fixup near .text?

Also, do you know what we see in r_info for a relocation that is
relative to a section rather than a symbol?

Paul.
