gold patch committed: Handle SHT_X86_64_UNWIND

[Ian Lance Taylor]

PR 12675 points out that gold doesn't correctly handle a .eh_frame
section with section type SHT_X86_64_UNWIND.  It would be nice if
.eh_frame always has a special section type, but it doesn't, so we must
continue to recognize it by name.  Given that, this patch changes gold
to treat SHT_X86_64_UNWIND as equivalent to SHT_PROGBITS when looking at
a .eh_frame section.  Committed to mainline.
