Hello,
I tried to figure how a standard waf build can be configured so that out-of-tree
or multiple build trees can be used. I couldn't get this working.
The Samba project seems to have support for out-of-tree builds:
https://wiki.samba.org/index.php/Waf#Out_of_tree_builds
However, this '-b' option is not present in a standard waf.
You would need to look for the additional options SAMBA must have added.
This looks like a project for the future.
The libbsd uses a common build tree for a list of arch/bsp combinations. This
seems to be quite a resource hungry solution. For example, I am not able to
build two BSPs with this approach on Windows/MSYS2.
What resources are you referring too, disk space, memory?
When I build two BSPs on Windows/MSYS2 I get this error:

Building the BSPs one after another works well.
Is there already a plan to build multiple BSPs (or one BSP with different
options) with waf?
Amar built more than one BSP, one after the other and so does rtems_waf. I have
not seen anything that would build a single BSP with different options using a
single configure command.
Ok, I figured it out more or less how you can build variants with waf.
