Utilizing clang seemed like the more resilient option moving forward, especially if we want to use newer C++ versions, but if we need gcc-cross-powerpc to compile glibc and compiler-rt then that's not a viable option. Are there any plans to support for these components moving forward?

There are no plans if the support is gone in gcc 9 that's a red flag
for OE to support, these days minimum version is gcc 10 for OE/Yocto
if you are using master branch.

you can do some hacks, if its just needed for u-boot -
