Sigh.  OK, I'll give it the path etc. for ld and as and nm.  I still
argue that before any of these are used in the build process they should
be checked to ensure that they match expectations.  I don't understand
the build process well, but these errors really need to show up in a
failed configure.  That would have avoided my mails on the subject and
saved me a few days of attempted gcc builds.

Thanks for bearing with me.  Please catch these issues in the
configurations somewhere if at all possible.  It'll save some people
several headaches :)

Thanks.
Nils.
