--- Comment #5 from John David Anglin <danglin at gcc dot gnu.org> ---
The problem is TREE_SYMBOL_REFERENCED is not set for libfuncs.  This fixes
problem on hppa64-hpux:

bash-5.1$ git diff gcc/varasm.cc

   pending_assemble_externals = 0;

If you don't care about libfuncs, you could move the TREE_SYMBOL_REFERENCED
check into the bpf target.
