Ahh. Debian 6.0 is getting quite old (2011), but yeah - People on
Enterprise distributions might end up with the same problems.

I don't think there's much we can do, besides perhaps adding a comment
in the help text.

I'm not sure how realistic it is to convince the Linaro people to build
their toolchains on ancient distributions.

I agree about linux32, yes.
