The "run" target will build the kernel and start it in QEMU. The "rerun" target will not have the kernel dependency and will just try to start QEMU. The QEMU architecture used to start the kernel is derived from the configured ARCH. This might need to be improved for archs which include different variants under the same name (mips vs mipsel, +/-64, riscv32 vs riscv64). This could be tested for i386, x86, arm, arm64, mips and riscv (the later two reporting issues on some tests).
It is possible to pass a test specification for nolibc-test in the TEST variable, which will be passed as-is as NOLIBC_TEST.
On success, the number of successful tests is printed. On failure, failed lines are individually printed.
