openWRT: please fix package/helloworld/Makefile - see logs/package/helloworld/dump.txt for details [solution]

When I tried to compile a `hello world' package for openWRT i had the following

ERROR: please fix package/helloworld/Makefile - see logs/package/helloworld/dump.txt for details

and inside dump.txt

....
Makefile:90: *** DESCRIPTION:= is obsolete, use Package/PKG_NAME/description.  Stop.


it seems that using description in the makefile is an old way so i just commented the description out and then compilation went with no errors.
