what is this being set to in do_conigure_prepend ?
that value may not be right for target recipe. For target we are setting sysroot to /
and if we do not have this option set then it will set native-system-headers dir to be
/ relative and not cross sysroot relative. So it will use your build hosts installation
for these headers which is not correct either. Have you looked deeper into why its not
finding ssp support inside the cross sysroot?
