[Slackbuilds-users] Desmume on 64-bit - optimization flag

[Larry Hajali]

Could just add an if statement that will add it to the SLKCFLAGS if it is
detected on the computer.

if grep [^s]sse3 /proc/cpuinfo 2>/dev/null; then
  SLKCFLAGS="$SLKCFLAGS -msse3"
fi

Not sure if this leads to undesirable results.  I don't have an sse3
capable processor, so I can't test.
