Is there a particular reason why this was done? As an experiment, I just removed the "--disable-libgomp" OECONF=20 additions from the GCC recipes, and added libgomp unconditionally (why=20 is that only included for powerpc?). Since multicore systems are getting more and more common even in=20 embedded systems, I guess I shouldn't be the only one who bumped into this.
