The HP linker for the hppa64-*-hpux* target lacks support for weak
undefined symbols. So,
we have a stub archive library to resolve various weak undefined
symbols. The attached change
adds a stub for the gnu_lto_v1 symbol. It is now needed for lto.
Tested on hppa64-hp-hpux11.11. Committed to trunk.
