Crashes on CPUs with no SSSE3 (legacy AMD ones)

[AceDolphin]

Hello
I am on arch linux and have compiled mcpe using the github instructions
https://github.com/minecraft-linux/mcpelauncher-manifest/wiki/Compiling-from-sources
I run pcpelauncher-ui-qt and when I click Play minecraft 1.7.0.13 the game crashes
This is the log that it shows after it crashes

Any help would be appreciated

Signal 4 is illegal instruction, so I'm afraid your hardware is too old (most likely and old AMD CPU w/o SSSE3)
