Add 2 testcases for PR ld/22269 Since undefined weak symbols in static PIE are always resolved to 0 at run-time, linker should resolve them as 0 at link-time, regardless of whether "-z dynamic-undefined-weak" is used. "-z dynamic-undefined-weak" only makes undefined weak symbols dynamic, but doesn't change undefined weak symbol resolution in static PIE at link-time. These tests currently pass on x86, but fails on many other targets. The framework to resolve weak symbols in static PE at link-time is posted at https://sourceware.org/ml/binutils/2017-10/msg00087.html which requires users/hjl/check_relocs branch to call check_relocs after opening all inputs. I will submit backend patches for failling targets after merging users/hjl/check_relocs branch next. * PR ld/22269 * testsuite/ld-elf/pr22269.s: New file. * testsuite/ld-elf/pr22269a.d: Likewise. * testsuite/ld-elf/pr22269b.d: Likewise. 2017-10-07 18:07:36 +08:00			`#name: PR ld/22269 (-z dynamic-undefined-weak)`
