The `bool serial` condition in scanRelocations disabled parallelism for three cases: -z nocombreloc, MIPS, and PPC64. Resolve two cases: - nocombreloc: .rela.dyn is now always created with combreloc=true so non-relative relocations are sorted deterministically. Since #187964 already separates relative relocations unconditionally, the only remaining effect of -z nocombreloc is suppressing DT_RELACOUNT (gated on ctx.arg.zCombreloc in DynamicSection). - PPC64: After #181496 moved scanning into scanSectionImpl, the sole thread-unsafe access is ctx.ppc64noTocRelax (DenseSet::insert). Protect it with ctx.relocMutex, which is already used for rare operations during parallel scanning. MIPS retains serial scanning due to `MipsGotSection` mutations.
