In the configure script we check for the presence of several basic
tools, like grep, sed, echo etc, and assign variables for them. In the
makefiles we are very diligent with always using the tools through these
variables to make sure we have a well functioning version of the tool at
hand. In many places in the configure script, we have been sloppy with
this.
I recently stumbled over this because we change the PATH variable in
parts of the script (typically when looking for the toolchain) which can
then potentially change which instance of the tool that is being run
unless the resolved variables are used. This patch fixes all the
instances that I could find.
