+++ This bug was initially created as a clone of Bug #98125 +++

As mentioned in PR98125, for 64-bit ELFv1 GCC 11 has a workaround where
compiler pretends linker doesn't support "o" section flag.
It would be good to find out how it can be supported in presence of .opd
section symbols, and either fix it on the assembler/linker side, or on the
compiler side or both.
