:-)  Zu englisch kann man auch "overkill" oder "killing a fly with a bazooka" sagen

I do check for it right at the beginning of crosstool.sh.
Checking for it at the beginning of all.sh might be nice,
but would be duplicated code.  I figure it's early enough as it is...

OK, thanks!

better.  (Actually, 'managed' mode is best, especially if you
want to build the linux kernel.)

What confusion did you run into there?

Thanks for the detailed problem report!
