pr20882 testcase
-gdwarf-sections doesn't work on targets that lack support to emit address size relative relocs. The testcase as it was avoided -gdwarf-sections doing anything by providing a non-empty .debug_line. It's better to not use -gdwarf-sections. Also, the testcase failed to match the output for 16-bit address targets like avr. PR ld/20882 * testsuite/ld-gc/pr20882.d: Don't pass -gdwarf-sections to gas. Allow for 16-bit address targets and match expected data fully. * testsuite/ld-gc/pr20882a.s: Delete .debug_line section. * testsuite/ld-gc/pr20882b.s: Likewise. * testsuite/ld-gc/pr20882c.s: Likewise.
