Wow, I didn't know the -i flag in sed.  You learn something new every day :-)

But rather than doing a substitution on the Makefile, you can also do this by
passing a parameter to make, like

preBuild = "
  makeFlagsArray=(SBINDIR=$out/sbin CONFDIR=$out/etc ...)
";

This is less sensitive to changes in the Makefile between releases.
