sparc: Fix la_symbind for bind-now (BZ 23734)
The sparc ABI has multiple cases on how to handle JMP_SLOT relocations, (sparc_fixup_plt/sparc64_fixup_plt). For BINDNOW, _dl_audit_symbind will be responsible to setup the final relocation value; while for lazy binding _dl_fixup/_dl_profile_fixup will call the audit callback and tail cail elf_machine_fixup_plt (which will call sparc64_fixup_plt). This patch fixes by issuing the SPARC specific routine on bindnow and forwarding the audit value to elf_machine_fixup_plt for lazy resolution. It fixes the la_symbind for bind-now tests on sparc64 and sparcv9: elf/tst-audit24a elf/tst-audit24b elf/tst-audit24c elf/tst-audit24d Checked on sparc64-linux-gnu and sparcv9-linux-gnu. Tested-by: John Paul Adrian Glaubitz <glaubitz@physik.fu-berlin.de> (cherry picked from commit dddc88587a7f48cbb361d9929ec23d790164eef8)
