ARM: Fix R_ARM_IRELATIVE RELA relocations.
This patch fixes what I believe to be a bug in the handling of R_ARM_IRELATIVE RELA relocations. At present, these are handled the same as REL relocations: i.e. the addend is loaded from the relocation address. Most of the time this isn't a problem because RELA relocations aren't used on ARM (GNU/Linux at least) anyway, but it causes problems with prelink, which uses RELA on all targets for its conflict table. (Support for ifunc prelinking requires a prelink patch, not yet posted.) Anyway, this patch works, though I'm not 100% sure if it is correct: I notice that this code path received attention last year: https://sourceware.org/ml/libc-ports/2013-07/msg00000.html I'm not sure under what circumstances that patch would have had an effect, nor if my patch conflicts with that case. No regressions using Mentor's usual glibc cross-testing infrastructure. [BZ #16888] * sysdeps/arm/dl-machine.h (elf_machine_rela): Fix R_ARM_IRELATIVE handling.
