(svn r5426) - Makefile: Make the configure script work properly for setting target compilers; Set CC_TARGET / CXX_TARGET

up the same way as CC_HOST / CXX_HOST, and add or fix their options within the configure script. In the 
Makefile, instead of overriding CC / CXX with the target compilers if they are set, set the target compilers 
with the default compilers if none are set (bit of a mouthful), and use the target compilers explicitly.
