Subject: knotty: Use non-interactive mode as fallback for dumb terminals
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=6f84cf4bd77f35fcd07e0b2f5149f1d6866a414d;p=thirdparty%2Fopenembedded%2Fopenembedded-core-contrib.git

knotty: Use non-interactive mode as fallback for dumb terminals

TERM=dumb bitbake X

shows no output for task status which is suboptimal. Use the non-interactive
mode if the terminal doesn't support what we need for interactive mode giving
a better user experience. Also print a note to the console to say this has
happened.
