Revised GCCE workaround for Bug 2926 - must use :zip export to ensure that the various files are present before any builds are attempted, otherwise there is "no rule to make usrt3_1.lib" and no attempt is made to link any executables even after the extension makefiles are executed.

For a description of the files and programs in this directory, see the
"Base How To Use Automated USB Tests" document
