[PATCH v2 0/8] Enable build system on macOS hosts

This patch set allows for building the Linux kernel for arm64 in macOS
with LLVM.
Patches are based on previous Nick's work and suggestions [1][2][3] to
enable the Linux kernel build system on macOS hosts.
macOS does not provide certain headers that are available in a GNU/Linux
distribution with development headers installed, usually provided by
the GNU C Library (glibc) and/or other projects. These missing headers
are needed as build dependencies. To address this, the patches depend
on a new Bee Headers Homebrew Tap formula [6][7][8] that provides them
together with a pkg-config file to locate the include directory.
To locate them, Makefiles include something like:
$(shell $(HOSTPKG_CONFIG) --cflags bee-headers 2> /dev/null)
[6] Project:
https://github.com/bee-headers
[7] Headers repository:
https://github.com/bee-headers/headers.git
[8] Homebrew Tap formula:
https://github.com/bee-headers/homebrew-bee-headers.git
To set up the environment, documentation is provided via last patch in
this series.
More configurations and architectures as well as support for Rust
(from Finn Behrens [4] [5]) can be added in the future to extend build
support.
