Summary: Our rule to create R_*_RELATIVE for absolute relocation types were loose. D63121 made it stricter but it failed to create R_*_RELATIVE for R_ARM_TARGET1 and R_PPC64_TOC. rLLD363236 worked around that by reinstating the original behavior for ARM and PPC64. This patch is an attempt to simplify the logic. Note, in ld.bfd, R_ARM_TARGET2 --target2=abs also creates R_ARM_RELATIVE. This seems a very uncommon scenario (moreover, --target2=got-rel is the default), so I do not implement any logic related to it. Also, delete R_AARCH64_ABS32 from AArch64::getDynRel. We don't have working ILP32 support yet. Allowing it would create an incorrect R_AARCH64_RELATIVE. For MIPS, the (if SymbolRel, then RelativeRel) code is to keep its behavior unchanged. Note, in ppc64-abs64-dyn.s, R_PPC64_TOC gets an incorrect addend because computeAddend() doesn't compute the correct address. We seem to have the wrong behavior for a long time. The important thing seems that a dynamic relocation R_PPC64_TOC should not be created as the dynamic loader will error R_PPC64_TOC is not supported.
