The imx-lib release, used in i.MX5, uses the old header file to check
for the license causing a build error:
ERROR: Function failed: imx-lib: LIC_FILES_CHKSUM points to an invalid file:
.../tmp/work/imx53qsb-poky-linux-gnueabi/imx-lib/11.09.02-r0/imx-lib-11.09.02/COPYING-LGPL-2.1
As the new releases will use the LGPL-2.1 license file we add the
override for the old release to avoid this build failure.
