[Buildroot] [PATCH] libtool: fix help2man related failure

[Gustavo Zacarias]

Libtool sometimes requires help2man to build manpages, but since we
don't use/need them and want to avoid pulling in and/or building
dependencies for that we just disable it. Fixes:
http://autobuild.buildroot.net/results/bfb/bfb9e298196d877b623580f882b6fe74b30bec9b/

Also add host-m4 as dependency, it's not strictly required but silences
many build warnings.

I was initially a bit worried by the new host-m4 dependency, but since
host-autoconf already depends on host-m4, in most situations, we build
both host-autoconf and host-libtool, so we're fine.

Applied, thanks!
