Extend the Makefile to be able to cross-compile open-iscsi

When cross-compiling you have to pass following with the make call:

1. CROSS_COMPILE=1
2. CROSS_BUILD_TYPE=target-triplet of the system on which the package is being
                    configured and compiled
3. CROSS_BUILD_HOST=target-triplet of the system on which the package will run
