Marking o32 objects with 64bit CPU is a long history gas behaviour, maybe appeared in 1990s, or even in the era of Irix.
I guess the reason is that to achive something like:

  -mabi=32 -march=octeon

`Octeon` is a 64bit CPU.
Since no matter about the -march value, due to all of them are using o32 abi,
they can interlink.
And thus Linux kernel uses this behaviour.
