[PATCH 3/4] devtool: add: prevent repeatedly running recipetool

[Paul Eggleton <paul.eggleton@linux.intel.com>]

If recipetool returns with exit code 14 this means devtool needs to
build nodejs-native and then call it again. If recipetool returns exit
code 14 again then clearly something has gone wrong and we should just
quit with an error.
