---Problem Description---
Latest glibc uses DT_RELR relocations, but linker support is incomplete as of binutils-2.38-3ubuntu1 on Ubuntu 22.04. It lacks the following fix integrated into the upstream 2.38 branch:
 
PowerPC64 DT_RELR relative reloc addresses
https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=e4a35c7319628045302d4c597cb27f1b0a08c858

As mentioned in the binutils mailing list when this patch was discussed, this fixes several glibc regressions:
