Build: Improved paths in local builds.

* CONFIG_LOCAL by default uses absolute paths,
  so you can execute run/bin/* from anywhere or
  directly use resulting *.pc by external commands.
* Define CONFIG_RELATIVE_PATHS for old relative paths.
* Removed SONAME_PREFIX, replaced with -rpath.

 Examples
 --------
   - `./configure -CONFIG_SHARED` will build the libraries statically.
   - `./configure -CONFIG_IMAGES` avoids building the image library.
   - `./configure CONFIG_UCW_ONLY -CONFIG_UCW_UTILS` compiles only the
     libucw library without its util programs.
-  - `./configure CONFIG_XML PREFIX=$HOME/sherlock` includes a xml
+  - `./configure CONFIG_XML PREFIX=$HOME/libucw` includes a xml
     library and installs into your home directory.
