Add dev name to labels

• Makefile now includes captors.mk which defines captor object files to build (the previous behaviour was to build all captors regardless of the captor selection during configuration)
• correct a bug in configure.sh : now properly detect amd cpu family
• configure.sh now print an error when 0 captors are selected
• configure.sh now do a make clean on successful configuration
• nvidia_gpu.c
