Please drop the "ARCH=parisc" in this prepare command, so this is sufficient:

	COMPILER_INSTALL_PATH=$HOME/0day COMPILER=gcc-11.2.0 make.cross O=build_dir       prepare

Since I'm not a GNU make/Makefile expert, I currently don't know how to prevent this
"FORCE prerequisite is missing" warning.
Any help is welcome here :-)
