GUB: gub-builder.py fails to build flex

[Pedro Kröger]

The command:

python gub-builder.py -p local build flex

fails because flex-2.5.4a.tar.gz unpacks to flex-2.5.4 (without the "a")
and gub-builder is trying to do:

tar -C /home/kroger/devel/gub/target/local/src -zcf
/home/kroger/devel/gub/uploads/local/flex-2.5.4a-src.local.gub flex-2.5.4a

but the directory "flex-2.5.4a" doesn't exist.
