OK, that all looks normal. This is getting strange - To summarize:

- Fails on Ubuntu (what version?), but not on Debian
- M4 check fails on autoconf2.64, works on 2.63 - But the M4 check is
  almost completely the same for the two versions
- The two tests done by the configure script succeeds when run by hand

Does it also fail if you prepend output/host/bin:output/host/usr/bin to
the path before running configure by hand (E.G. a setup very close to
how it's done in buildroot)?

It's hard for me to debug it here as I cannot reproduce it. It would be
very helpful if you could add a few debug echo lines to ./configure
around line 2356, so we can see what's going on.
