This fails on i686-linux regtest when linker plugin is disabled (I use that
in my setup, because my ld is 64-bit and 32-bit plugins don't really work
very well with 64-bit linker).
The problem is that XYZ is extern in both sources, no idea why it actually
works with linker plugin. That said, dropping extern from one of the two
doesn't really work, the ICE when the fix is reverted goes away.
But with the following change the ICE is still in there when
r268789 and r268981 is reverted (both in this i686-linux setup and normal
x86_64-linux with linker plugin), and with vanilla cc1/lto1 works.
So, I've committed this to trunk as obvious.
