I had a look to your test case, I think the second command is not
correct. The T= parameter is not allowed for the clean target. It
should be something like this:
# configure a workspace using template specified by T= in the
# directory specified by O=
make T=x86_64-native-linuxapp-gcc O=x86_64-native-linuxapp-gcc config
# clean the directory specified by O=
make O=x86_64-native-linuxapp-gcc clean
See "make help" for details.
I think the proper patch would be to add the following lines on the
top of rte.sdkbuild.mk:
ifdef T
ifeq ("$(origin T)", "command line")
$(error "Cannot use T= with a build/clean target")
endif
endif
It would then display the proper error message.
Can you have a try?

Olivier
