Signal 4 is SIGILL, usually indicating the process in question was using an instruction that is not supported by the host processor.
The change that brings in this was https://android-review.googlesource.com/c/platform/art/+/441015 and according to the specification I have found for AMD C-60, it doesn't have SSE 4.2 support, but it does support POPCNT instruction, so I think removing -msse4.2 should actually be sufficient. Newer AMD processors (Bulldozer, Piledriver, Steamroller, Excavator and all Zen and newer processors) supports all these instructions, and using these would result quite visible build performance improvements on the new CPUs. This affects ART tools that runs on host, and they shouldn't affect the final build result.
