Isn't the format of that section mandated by lto-plugin though?

And here are the IR symtabs (I built a cross GCC just far enough to get the
liblto_plugin):

The problem is that first one is defined as prevailing_def_ironly while it is
not an definition, just use of the symbol. Correct

What endian-ness are the ppc and hppa targets?
hppa is big. I believe ppc is also big.

Merging should happen after unmerged files are dumped. Perhaps they go to some
