Log Message:
-----------
configure: fix detection for x32 linux-user
x32 uses the same signal handling fragments as x86_64, since host_arch
is set to x86_64 when Meson runs. Remove the unnecessary forwarder and
set the host_arch variable properly in configure.

linux-user: cleanup unused linux-user/include/host directories
Alpha and 31-bit s390 lack the assembly fragment to handle signals
occurring at the same time as system calls, so they cannot run
linux-user emulation anymore. Drop the host-signal.h files for
them.

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.

linux-user: Rewrite non-fixed probe_guest_base
Use pgb_addr_set to probe for all of the guest addresses,
not just the main executable. Handle the identity map
specially and separately from the search.
If /proc/self/maps is available, utilize the full power
of the interval tree search, rather than a linear search
through the address list.
If /proc/self/maps is not available, increase the skip
between probes so that we do not probe every single page
of the host address space. Choose 1 MiB for 32-bit hosts
(max 4k probes) and 1 GiB for 64-bit hosts (possibly a
large number of probes, but the large step makes it more
likely to find empty space quicker).
