Added script to build LinCAN project independent of OCERA tree.

Added script to build LinCAN project independent of OCERA tree.

The code represented in this repository is in directory is based
on the LinCAN (ocera/components/comm/can/lincan directory) component
from OCERA (IST-2001 35102) project. Original project documentation
can be found there
  http://www.ocera.org/download/components/WP7/index.html
  http://sourceforge.net/projects/ocera/
  http://ocera.cvs.sourceforge.net/ocera/ocera/components/comm/can/

Can related components CVS repository can be accessed by
  cvs -d:pserver:anonymous@ocera.cvs.sourceforge.net:/cvsroot/ocera login
  cvs -z3 -d:pserver:anonymous@ocera.cvs.sourceforge.net:/cvsroot/ocera co ocera/components/comm/can

The original code depend on OCERA make system. The minimal set of OMK <http://rtime.felk.cvut.cz/omk/>
rules has been introduced in the previous changeset to make this project independent
of full OCERA repository.

The scrip "build-lincan.sh" prepares "lincan-build/native" directory and links
OMK rules and unmodified LinCAN directory there. Then it builds native version
of the driver for current running kernel. Resulting driver can be found
in directory
  lincan-build/native/_compiled/modules
Utilities binaries are located in directories listed bellow
  lincan-build/native/_compiled/bin
  lincan-build/native/_compiled/bin-utils
