x86: Remove empty X86_FEATURE_1_AND property
There is no need to generate .note.gnu.property section with empty
X86_FEATURE_1_AND property. This patch adds fixup_gnu_properties
to ELF linker backend so that x86 backend can remove it.

* elf-bfd.h (elf_backend_data): Add fixup_gnu_properties.
* elf-properties.c (_bfd_elf_link_setup_gnu_properties): Call
backend fixup_gnu_properties if it isn't NULL. Discard
.note.gnu.property section if all properties have been removed.
* elfxx-target.h (elf_backend_fixup_gnu_properties): New.
(elfNN_bed): Initialize fixup_gnu_properties.

prototype.
