Browse Source 
Inserted offset in final section in the GOT entry of type DTSOFF soon to be
relocated by the dynamic loader.

2018-09-06  Cupertino Miranda <cmiranda@synopsys.com>

	* arc-got.h (relocate_fix_got_relocs_for_got_info): Changed. Take TLS
	    section alignment in consideration for this relocation.
	* elf32-arc.c (FINAL_SECTSTART): Added this formula macro.
	  (ARC_TLS_DTPOFF) Updated reloc to use new created macro instead.
