Ok, this has been going on since -rc1, which is much too long.
From your patch submission that that was rejected:
The problem was introduced with commit 41b7a347bf14 ("powerpc: Book3S
64-bit outline-only KASAN support") which adds support for KASAN. This
commit in turn enables DRM_AMD_DC_DCN because KCOV_INSTRUMENT_ALL and
KCOV_ENABLE_COMPARISONS are no longer enabled. As result, new files are
compiled which lack the selection of hard-float.
And considering that neither the ppc people nor the drm people seem
interested in fixing this, and it doesn't revert cleanly I think the
sane solution seems to be to just remove PPC64 support for DRM_AMD_DC
IOW, does something like this (obviously nor a proper patch, but you
get the idea) fix the ppc build for you?

Choose this option if you want to use the new display engine
support for AMDGPU. This adds required support for Vega and
