SHF_LINK_ORDER fixup_link_order in ld
This moves the SHF_LINK_ORDER sorting from bfd_elf_final_link to
the linker which means generic ELF targets now support SHF_LINK_ORDER
and we cope with odd cases that require resizing of output sections.
The patch also fixes two bugs in the current implementation,
introduced by commit cd6d537c48fa. The pattern test used by that
commit meant that sections matching something like
"*(.IA_64.unwind* .gnu.linkonce.ia64unw.*)" would not properly sort a
mix of sections matching the two wildcards. That commit also assumed
a stable qsort.
