Subversion's Berkeley DB detection with APR trunk

apr trunk combines apr and apr-util into a single library and there is
only a single apr-2-config script. Subversion can be configured by
using this script for both apr and apr-util, but Subversion's Berkeley
DB detection doesn't work. This is because the apr-2-config script
doesn't support the --db-version parameter that the old apu-config
script provided.

Should we rework Subversion's Berkeley DB detection or should we change
APR?
