[PATCH] strip: Remove SUNW_symtabsort and .SUNW_symtabnsort sections

[H.J. Lu]

On Solaris, SUNW_symtabsort and .SUNW_symtabnsort sections are linked
with .symtab and .strtab sections.  Since strip always removes .symtab
and .strtab sections, also removes .SUNW_symtabsort and .SUNW_symtabnsort
sections to silence:

strip: striprog: failed to find link section for section 27
strip: striprog: failed to find link section for section 27
strip: striprog: failed to find link section for section 28
strip: striprog: failed to find link section for section 28

	* objcopy.c (is_strip_section_1): Remove .SUNW_symtabsort
	and .SUNW_symtabnsort for Solaris.
