We currently require the variable CROSS (or CROSS_COMPILE) to be set to specify the global cross-compilation prefix. This becomes cumbersome when developing across multiple CPU architectures, requiring frequent editing of build command lines and preventing incompatible architectures from being built with a single command. Allow a default cross-compilation prefix for each architecture to be specified via the CROSS_COMPILE_<arch> variables. These may then be provided as environment variables, e.g. using export CROSS_COMPILE_arm32=arm-linux-gnu- export CROSS_COMPILE_arm64=aarch64-linux-gnu- export CROSS_COMPILE_loong64=loongarch64-linux-gnu- export CROSS_COMPILE_riscv32=riscv64-linux-gnu- export CROSS_COMPILE_riscv64=riscv64-linux-gnu- This change requires some portions of the Makefile to be rearranged, to allow for the fact that $(CROSS_COMPILE) may not have been set until the build directory has been parsed to determine the CPU architecture.
