Yes, as Per has suggested, this should work out of the box. In fact,
/usr/local is system-installed, at least from build2's POV.

It's also not unreasonable to want to use such packages directly
from the build configuration without first installing them, And
this won't work as smoothly. So at some point we may want to
consider supporting "overlay configuration" or some such.
