For SVE, currently the bulk of the GDB TCG tests, we need at least GDB
9.1 to support the "ieee_half" data type we report. This only affects
when GDB tests are run; users can still use lower versions of gdb as
long as they aren't talking to an SVE enabled model. The work around
is to either get a newer gdb or disable SVE for their CPU model.

When checking GDB versions we have to tolerate all sorts of random
distro extensions to the version string. While we already attempt to
do some of that before we call version_ge is makes sense to try and
regularise the first input by stripping extraneous -'s. While we at it
convert the old-style shell quoting into a cleaner form t shut up my
editors linter lest it confuse me by underlining the whole line.

Replace the --enable-git-update and --disable-git-update configure params
with the param --with-git-submodules=(update|validate|ignore) to
allow 3 options for building from a git repo.

This is needed because downstream packagers, e.g. Debian, Ubuntu, etc,
also keep the source code in git, but do not want to enable the
'git_update' mode; with the current code, that's not possible even
if the downstream package specifies --disable-git-update.

The previous parameters are deprecated but still available; the
--enable-git-update parameter maps to --with-git-submodules=update and
--disable-git-update parameter maps to --with-git-submodules=validate.

The configure script behavior is slightly modified, where previously
the dtc, capstone, and slirp submodules were not validated when
--disable-git-update was specified (but were updated with git-update
enabled), now they are validated when using --with-git-submodules=validate
and are only ignored when using --with-git-submodules=ignore.

A workaround added in early days of 64-bit OSX forced x86_64 if the
host machine had 64-bit support. This creates issues when cross-
compiling for ARM64. Additionally, the user can always use --cpu=* to
manually set the host CPU and therefore this workaround should be
removed.

Move the preadv availability check to meson.build.  This is what we
want to be doing for host-OS-feature-checks anyway, but it also fixes
a problem with building for macOS with the most recent XCode SDK on a
Catalina host.

On that configuration, 'preadv()' is provided as a weak symbol, so
that programs can be built with optional support for it and make a
runtime availability check to see whether the preadv() they have is a
working one or one which they must not call because it will
runtime-assert.  QEMU's configure test passes (unless you're building
with --enable-werror) because the test program using preadv()
compiles, but then QEMU crashes at runtime when preadv() is called,
with errors like:

  dyld: lazy symbol binding failed: Symbol not found: _preadv
    Referenced from: /Users/pm215/src/qemu/./build/x86/tests/test-replication
    Expected in: /usr/lib/libSystem.B.dylib

  dyld: Symbol not found: _preadv
    Referenced from: /Users/pm215/src/qemu/./build/x86/tests/test-replication
    Expected in: /usr/lib/libSystem.B.dylib

Meson's own function availability check has a special case for macOS
which adds '-Wl,-no_weak_imports' to the compiler flags, which forces
the test to require the real function, not the macOS-version-too-old
stub.

So this commit fixes the bug where macOS builds on Catalina currently
require --disable-werror.

There are two cases that need to be accounted for when compiling QEMU
for MinGW32:
 1) A standalone distribution, where QEMU is self contained and
    extracted by the user, such as a user would download from the QEMU
    website. In this case, all the QEMU executable files should be
    rooted in $prefix to ensure they can be easily found by the user
 2) QEMU integrated into a distribution image/sysroot/SDK and
    distributed with other programs. In this case, the provided
    arguments for bindir/datadir/etc. should be respected as they for a
    Linux build.

Restructures the MinGW path configuration so that all of the paths
except bindir use the same rules as when building for other platforms.
This satisfies #2 and #1 since these files do not need to be directly in
$prefix anyway.

The handling for --bindir is changed so that it defaults to $prefix on
MinGW (maintaining the compatibility with #1), but if the user specifies
a specific path when configuring it can also satisfy #2.

The support of socket based debugging which we need for linux-user
testing is only really stable as of 8.3.1 so lets gate our use of GDB
on having a relatively modern version.

For direct testing you can just point to a locally compiled version of
gdb via configure, e.g.:

  ../../configure --gdb=$HOME/src/binutils-gdb.git/builds/all/install/bin/gdb
