This is the first time I have needed to set -march,
despite having
compiled (literally) hundreds of applications from source. There's
clearly something specific to yoshimi that is triggering this,
Yoshimis CPU-feature detection more or less sucks :)
I managed to compile a couple of versions that segfaulted upon start
before I realized that ccmake thought my Athlon-XP 2000+ had the SSE2
instruction set.
