Minimum `rustc` version required for powerpc is 1.95 as some critical
features required for compiling rust code for kernel are not there.

For example Stable inline asm support which got merged in 1.95.

Didn’t we decide on 1.85.0 with the asm_experimental_arch feature
instead?  And possibly on 64-bit 1.87.0 if it isn’t possible to disable
altivec correctly there?

1.85.0 or 1.85.1 is not feasible for ppc64le.
PPC maintainer is ok with 1.95 for PPC. It's still experimental for PPC.
