I am afraid that inheriting of <library> feature is currently broken, so this
won't work. What will work, however, is this (in top-level Jamfile)

   lib foo ;

   project test : requirements <library>/test//foo ;

Here, we use absolute id of the target, and so subproject will have no
problems accessing it.

It's also possible to do this:

   # Get all child Jamfiles
   local sub = [ glob */Jamfile ] ;
   # Strip filenames, getting just directories;
   sub = $(sub:D) ;
   for local s in $(sub)
                build-project $(s) ;
