        external/gpl3/binutils/dist/bfd/elflink.c: revision 1.14
When trying to decide the status of a weak symbol, resolve any
indirectness first. In the case of various Qt5 libraries, __bss_start
ends up with a Qt5 version, but it has to be resolved first to match the
actual (implicit) definition. This fixes the root cause of pkg/53089.
