I have used your patch to bootstrap with GCC 12 (in order to use both
gcc-12 and llvm-14 in the same profile) and I have found that without
"glibc-ldd-x86_64.patch", sometimes ldd will throw a "not a dynamic
executable" error. I assume the powerpc patch is likewise still
required.

I would like to see the 2.35 upgrade since others may benefit before
the 2.36 release and in case of a core-updates merge to master.
