Good point. So far all my boards are very similar so this hasn't been a
problem, but that won't always be the case.
IMHO this is a flaw of the project support - everything should be built
into a project-specific directory. Currently only the kernel and busybox
are built in project_build_$arch.
How would everyone react to a patch which redefines BUILD_DIR to match
PROJECT_BUILD_DIR, ie each project would have
I think Ulf commented in the past that he doesn't want to waste the time
spent compiling each package for each board separately, but that seems
to be the only way to do it correctly.
