Is this a regression? Has this compiler ever been able to build this
arch like this?

Yes. It is a regression with gcc-11.
stable rc Linux 5.13.14 with gcc-11 - powerpc - FAILED

No.
stable rc Linux 5.14.1-rc1 with gcc-11 - powerpc - FAILED
stable rc Linux 5.14.1-rc1 with gcc-10 - powerpc - PASS
I will check Linux mainline and Linux next and get back to you.

Since we started building with gcc-11 last weekend and started
noticing these build failures on stable-rc, mainline and next.
and today's stable-rc review also failed with these combinations.
Linux next master with gcc-11 - powerpc-defconfig - FAILED
Linux mainline master with gcc-11 - powerpc-defconfig - FAILED
stable rc Linux 5.14.2-rc1 with gcc-11 - powerpc-defconfig - FAILED
stable rc Linux 5.13.15-rc1 with gcc-11 - powerpc-defconfig - FAILED
stable rc Linux 5.10.63-rc1 with gcc-11 - powerpc-defconfig - FAILED
FYI,
The following powerpc config build PASS with gcc-11
- allnoconfig
- mpc83xx_defconfig
- tqm8xx_defconfig
- maple_defconfig
- cell_defconfig
- ppc64e_defconfig
- ppc6xx_defconfig
