[PATCH] build/buildcheck.sh: check also autoheader

Hi!

This very small pacth add test for autoheader. I think that this is
relevant if user set AUTOCONF, but forget set AUTOHEADER. I also add
some advertisement about those variable to error message.

The patch has been generated against version 3425.

Log message:

* build/buildcheck.sh : Add check also for autoheader, and made output
  more verbose in case that wrong version of autoconf/autoheader has been
  found.
