From: Ross Burton <ross.burton@arm.com>

inetutils guesses a lot of target paths in cross builds, and warns that
some of them are known to be wrong (for example, whether /proc/net/dev
exists is guessed as 'no').

Add a post-configure function to check for these warnings, and pass
--with-path-* as appropriate to set the paths explicitly.

This means we can remove the patch which was setting PATH_PROCNET_DEV,
and the autoconf cache value inetutils_cv_path_login.

The downside is that these --with-path-* options are not real autoconf
options, so the "unknown options" warning is emitted.  Losing those is
an acceptable compromise, so disable it.
