The CPU model has to be canonicalized to what Meson wants in the cross file, to what Linux uses for its asm-$ARCH directories, and to what QEMU uses for its user-mode emulation host/$ARCH directories. Do all three in a single case statement, and check that the Linux and QEMU directories actually exist.At a small cost in repeated lines, this ensures that there are no hidden ordering requirements between the case statements. In particular, commit 89e5b7935e9 ("configure: Fix linux-user host detection for riscv64", 2023-08-06) broke ppc64le because it assigned host_arch based on a non-canonicalized version of $cpu.
