From 2a70ed792f883b8340099d74b2f325b2ca01616b Mon Sep 17 00:00:00 2001

Subject: introduce support for sdkroot and sysroot to support cross-builds

To allow building for another location rather the final install prefix,
regardless whether chroot based builds, cross-compile or canadian cross sdk
is the goal, realize the difference between prefix, the sdk-root and the
system root for final target.
