ENV/shared: handle untapped e.g. gcc48 formula.

In this case we need to handle the throwing on an exception when
attempting to initialize the gcc48 Formula object.

This initialization should be unnecessary if the core GCC is already
installed and rescued if not.
xulrunner 29.0 (devel 30.0b1)
xulrunner: update 29.0 bottle.

Closes #28825.

brew-test-bot: handle failing devel requirements.
Superenv: determine_optflags should return a string

This is saved in HOMEBREW_OPTFLAGS and later mutated by
ENV.universal_binary, so if this returns nil the sub will fail.

bencode-tools isn't well-known or used enough to justify its own
formula at this point in time, but it's a dependency for the HEAD
version of UADE.
