* elf64-sparc.c (sparc64_elf_adjust_dynamic_symbol): When linking a

Browse Source 
non-shared object, do not reserve space in .plt and .rela.plt
for regular symbols neither defined nor referenced in shared objects.

This is a backport of rev. 1.101 (sourceware.org repository) to
Binutils 2.15 which fixes the creation of bogus relocations in the
PLT of Firefox and Thunderbird binaries and which in turn caused
them to segfault in rtld(1). This is committed to the vendor branch
as it doesn't represent a local change but the original vendor fix
is from after elf_link_hash_flags was replaced with bitfields.
