To support -z mark-plt enabled by default, adjust x86 tests to accept non-zero r_addend for JUMP_SLOT relocation and pass -z nomark-plt to x86-64 tests if -z mark-plt changes the expected outputs. * testsuite/ld-elf/indirect-extern-access-2.rd: Allow non-zero r_addend for JUMP_SLOT relocation. * testsuite/ld-elf/pr23161d.rd: Likewise. * testsuite/ld-ifunc/ifunc-25c-x86.d: Likewise. * testsuite/ld-ifunc/ifunc-16-x86-64-now.d: Pass -z nomark-plt to linker. * testsuite/ld-ifunc/ifunc-16-x86-64.d: Likewise. * testsuite/ld-ifunc/ifunc-2-local-x86-64-now.d: Likewise. * testsuite/ld-ifunc/ifunc-2-local-x86-64.d: Likewise. * testsuite/ld-ifunc/ifunc-2-x86-64-now.d: Likewise. * testsuite/ld-ifunc/ifunc-2-x86-64.d: Likewise. * testsuite/ld-ifunc/ifunc-20-x86-64.d: Likewise. * testsuite/ld-ifunc/ifunc-5b-x86-64.d: Likewise. * testsuite/ld-ifunc/pr17154-x86-64-now.d: Likewise. * testsuite/ld-ifunc/pr17154-x86-64.d: Likewise. * testsuite/ld-x86-64/dt-relr-1a-x32.d: Likewise. * testsuite/ld-x86-64/dt-relr-1a.d: Likewise. * testsuite/ld-x86-64/dt-relr-1b-x32.d: Likewise. * testsuite/ld-x86-64/dt-relr-1b.d: Likewise. * testsuite/ld-x86-64/ibt-plt-2a-x32.d: Likewise. * testsuite/ld-x86-64/ibt-plt-2a.d: Likewise. * testsuite/ld-x86-64/ibt-plt-3a-x32.d: Likewise. * testsuite/ld-x86-64/ibt-plt-3a.d: Likewise. * testsuite/ld-x86-64/pr19636-2d.d: Likewise. * testsuite/ld-x86-64/pr19636-2e.d: Likewise. * testsuite/ld-x86-64/pr19636-2f.d: Likewise. * testsuite/ld-x86-64/pr19636-2l.d: Likewise. * testsuite/ld-x86-64/x86-64.exp: Pass -z nomark-plt to linker in 6 tests.
