Also, IIUC, this patch is not related to LTO, because if ld.gold doesn't

That's correct. ld.gold --help says -m is obsolete, but at the same time,
it supports a number of emulations, just with different names than ld.bfd.
I'll take a closer look at this and see if there's a different flag we
should be passing here instead. Looks like I also have some 0-day issues
to address for v2.
