Introduce fallback for general cross compilation

The current approach of forcing people to pass the fully qualified prefix
of their toolchain to the configure script is verbose and something of a
chore for people who use the same toolchain to target several devices.

This allows you to set a single toolchain for use with all Qt targets via:

qmake -set CROSS_COMPILE foo

You can still explicitly override this toolchain, as originally mandated,
with the configure time device-option arguments.
