Subject: Don't generate static device files at install time.

* Most users use udev anyway
* Don't attempt to create any device files in the 'install' target.
* Setting DYNFS at build time should no longer be needed
  - Though remains harmless.
* In order to create the static device files, use the script:

  build_tools/make_static_devs

+Static Device Files
+~~~~~~~~~~~~~~~~~~~
+Userspace programs communicate with the DAHDI modules through special
+device files under /dev/dahdi .  Those are normally created by udev, but
+if you use an embedded-type system and don't wish to use udev, you can
+generate them with the following script, from the source directory:
+
+  ./build_tools/make_static_devs
+
+This will generate the device files under /dev/dahdi . If you need to
+generate them elsewhere (e.g. `tmp/newroot/dev/dahdi`) use the option -d
+to the script:
+
+  ./build_tools/make_static_devs -d tmp/newroot/dev/dahdi
