971fac2731e60f2143f35648b14fd2f1b5b2c1af configure: unify case statements for CPU canonicalization
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.
