-B must be set to the root directory of avrlibc, otherwise gcc cannot locate crt objects for some attiny devices. -L trains as set by bintools-wrapper are not necessary with -B set correctly because gcc takes care of that, and likewise we can drop the -B train from cc-wrapper because the one spec is enough.
