Hello fellow devs,
Please review the attached qt4-build-multilib.eclass ASAP. It's
basically the current qt4-build.eclass with some old cruft removed and
multilib support added.
Given the amount of changes needed for multilib, we chose to introduce
a separate eclass rather than modifying the existing one, to avoid
destabilizing current consumers and to maintain code readability.
While at it, we also refactored the code quite a bit, and rewrote some
functions using a more modern style.
Thanks,
Davide Pesavento
