The $(comma) variable is not defined in this Makefile, nor in
any included Makefile. Seen while doing a "make clean" on ubuntu:
$ make clean
== Clean lib
== Clean lib/librte_compat
== Clean lib/librte_eal
== Clean lib/librte_eal/common
== Clean lib/librte_eal/linuxapp
== Clean lib/librte_eal/linuxapp/eal
== Clean lib/librte_eal/linuxapp/igb_uio
== Clean lib/librte_eal/linuxapp/kni
tr: missing operand after ?.-?
Two strings must be given when translating.
Try 'tr --help' for more information.
This commit replaces $(comma) by a ',' character, it's not a problem in
that case since we are inside antiquotes.
