Ok, that's a different issue than Johan's then - The snippet he posted
was about autoconf for the target.

Strange as the host-autoconf package depends on host-m4. Don't you have
a build/m4-1.4.9-host directory? On my system I get:

configure:2356: checking for GNU M4 that supports accurate traces
configure:2398: result: /tmp/br/host/usr/bin/m4
configure:2401: checking whether /tmp/br/host/usr/bin/m4 accepts --gnu
configure:2411: result: no

I don't see why it shouldn't work, but I've just started such a build
anyway.
