Radomir Dopieralski 55fbbdcb52 Allow enabling async on samd21 
It was just disabled, possibly because of size considerations, but it's
useful to be able to enable it explicitly for selected boards.

This requires some of the settings to use ?= instead of =, and fixing
a bug in the traceback module, where the chain variable is unused if
exception chaining is not enabled.
