What this doesn't say is "because they were GNU extensions for
embedded-PIC support which weren't copied to the n32/64 support in
BFD, apparently." 8-)

Right, so, then, which is *correct*?
I'd say that the mips64-linux-gnu version is the "better" one, since
the PC-relative 32/64 relocations were non-standard.
But I have no idea how much pain would be caused by switching. Or
whether (and how much) backward-compatibility needs to be maintained.
