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...

want to build the linux kernel.)

What confusion did you run into there?

Thanks for the detailed problem report!
