We already prefer ld for cross-building arm64 but that seems
not enough as native arm64 build also has a linker issue with lld
so we need to also prefer ld for native arm64 build.

Static binaries for dockerd are broken on armhf and armel (32-bit).
It seems to be an issue with GCC as building using clang solves
this issue. Also adds extra instruction to prefer ld for
cross-compiling arm64 in bullseye otherwise it doesn't link.

Disables user.Lookup() and net.LookupHost() in the init() function on Windows.
Any package that simply imports pkg/chrootarchive will panic on Windows
Nano Server, due to missing netapi32.dll. While docker itself is not
meant to run on Nano Server, binaries that may import this package and
run on Nano server, will fail even if they don't really use any of the
functionality in this package while running on Nano.

Current implementation in hack/make.sh overwrites PKG_CONFIG
if not defined and set it to pkg-config. When a build is invoked
using xx in our Dockerfile, it will set PKG_CONFIG to the right
value in go environments depending on the target architecture: 8015613ccc/base/xx-go (L75-L78)
Also needs to install dpkg-dev to use pkg-config when cross-building

Build currently doesn't set the right name for target ARM
architecture through switches in CGO_CFLAGS and CGO_CXXFLAGS
when doing cross-compilation. This was previously fixed in https://github.com/moby/moby/pull/43474
Also removes the toolchain configuration. Following changes for
cross-compilation in https://github.com/moby/moby/pull/44546,
we forgot to remove the toolchain configuration that is
not used anymore as xx already sets correct cc/cxx envs already.

This reverts commit 2d397beb00.
moby#44706 and moby#44805 were both merged, and both refactored the same
file. The combination broke the build, and was not detected in CI as
only the combination of the two, applied to the same parent commit,
caused the failure.
moby#44706 should be carried forward, based on the current master, in
order to resolve this conflict.

Embedded structs are part of the exported surface of a struct type.
Boxing a struct value into an interface value does not erase that;
any code could gain access to the embedded struct value with a simple
type assertion. The mutex is supposed to be a private implementation
detail, but *network implements sync.Locker because the mutex is
embedded. Change the mutex to an unexported field so *network no
longer spuriously implements the sync.Locker interface.

Basically every exported method which takes a libnetwork.Sandbox
argument asserts that the value's concrete type is *sandbox. Passing any
other implementation of the interface is a runtime error! This interface
is a footgun, and clearly not necessary. Export and use the concrete
type instead.
