Some cross compilers may not just be prefixed with ARCH, customize them by architecture may simplify the test a lot, especially, when iterate with ARCH.
After customizing this for every architecture, the minimal test argument will be architecture 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_<ARCH>.
