Add a new tag (Tag_ARC_ATR_version) used to indicate if current attributes are interpreted in GNU way. This attribute is used by Synopsys custom compiler to correctly identify and interpret the object attributes section as generated by GNU tools. gas/ 2017-08-02 Claudiu Zissulescu <claziss@synopsys.com> * config/tc-arc.c (arc_set_public_attributes): Add Tag_ARC_ATR_version.
