Error in marshmallow branch's hardware/aw/Anroid.mk file

While making the marshmallow branch, following error was encountered:
make: *** No rule to make target `hardware/aw/widevine/adapt_semelis/widevine_L/Android.mk'.  Stop.
Seems that there is no "widevine_L" directory, but "widevine_L1" & "widevine_L3" directories
