[Bug binutils/778] New: Hiding _GLOBAL_OFFSET_TABLE_ breaks function pointer canonicalization

[danglin at gcc dot gnu dot org]

This change breaks the linker on hppa-unknown-linux-gnu:

2004-11-02  Hans-Peter Nilsson  <address@hidden>

        * elflink.c (_bfd_elf_create_got_section): Hide _GLOBAL_OFFSET_TABLE_.

It introduces the following fails in the ld testsuite:

.

See gcc/config/pa/fptr.c to see why we need access to this symbol
on this target.  This

case.
