You should be able to do "bitbake meta-toolchain-qt5 angstrom-lxde-image" in 
one go. That should be faster than two separate runs.

If you change the DISTRO, you'll invalidate your "tmp" building dir resulting 
in loads of new stuff being built.

If you need two distros, make two build enviroments from them. You should 
share the sstate-cache directory between them (saves tons on building 
compilers and such) but not the "tmp" directory.
