Some cross compilers are not just prefixed with XARCH, customize them by architecture may simplify the test a lot, especially, when iterate with XARCH. After customizing this for every architecture or its variant, the minimal test argument will be architecture or variant itself, no CROSS_COMPILE required to be passed. If the prefix of installed cross compiler is not the same as the one customized, we can also pass CROSS_COMPILE as before or even pass CROSS_COMPILE_$(XARCH) and CC from command line.
