On some machines, in incremental builds I still seeing this: Assembler messages: Error: unknown architectural extension `lse' Error: unrecognized option -march=armv8-a+lse make[4]: *** [load_1_1_.lo] Error 1 make[4]: *** Waiting for unfinished jobs.... Looks related... the only strange thing happening is that this doesn't happen in full builds. -- Paulo Matos
