[ARC] Fix parsing dtpoff relocation expression.
The assembler accepts dtpoff complex relocation expression like identifier@dtpoff + const. However, it doesn't accept an expression such as identifier@dtpoff@base + const. This patch solves this issue, and adds a number of tests. ld/ 2016-09-14 Claudiu Zissulescu <claziss@synopsys.com> * testsuite/ld-arc/tls-dtpoff.dd: New file. * testsuite/ld-arc/tls-dtpoff.rd: Likewise. * testsuite/ld-arc/tls-dtpoff.s: Likewise. * testsuite/ld-arc/tls-relocs.ld: Likewise. * testsuite/ld-arc/arc.exp: Add new tdpoff test. gas/ 2016-09-14 Claudiu Zissulescu <claziss@synopsys.com> * testsuite/gas/arc/tls-relocs2.d: New file. * testsuite/gas/arc/tls-relocs2.s: Likewise. * config/tc-arc.c (tokenize_arguments): Accept offsets when base is used.
