	* elflint.c (check_symtab): Check that _GLOBAL_OFFSET_TABLE_ st_shndx
	refers to the right section if it's not SHN_ABS.
	Let ebl_check_special_symbol override _G_O_T_ value and size checks.

	* elflint.c (check_sections): Don't complain about a non-NOBITS
	section taking no segment space, if it's sh_size is 0.

	* elflint.c (check_sections): Use ebl_bss_plt_p to see if .plt should
	be PROGBITS or NOBITS.

	* elflint.c (check_symtab): Use ebl_check_special_symbol to override
	standard st_value and st_size checks.
