When I build clang-16 from your object files (plus my system libraries and startup files) for powerpc64le using gold 2.40.50.20230614 I get exactly the same binary as when using gold 2.39.0.20230101. That's comparing gold from the tip of master and binutils-2_39-branch in sourceware.org/git/binutils-gdb.git. The latter does not have the commit you identify as causing a problem.
Very likely the reason why I don't see a problem is that my libz.so.1, libtinfo.so.5, libstdc++.so.6, libm.so.6, libgcc_s.so.1, libc.so.6, ld64.so.2, or startup files are different to yours. -- You
