	When building in a portage chroot, we do not have the environment needed to build pylibfdt. It is instead build as a separate package. Provide a build option to tell U-Boot to skip this part of the build. We still need it to use binman, etc. but don't need it to build its dependencies.

Host tools
 | 
						|
==========
 | 
						|
 | 
						|
Building tools for Linux
 | 
						|
------------------------
 | 
						|
 | 
						|
To allow distributions to distribute all possible tools in a generic way,
 | 
						|
avoiding the need of specific tools building for each machine, a tools only
 | 
						|
defconfig file is provided.
 | 
						|
 | 
						|
Using this, we can build the tools by doing::
 | 
						|
 | 
						|
   $ make tools-only_defconfig
 | 
						|
   $ make tools-only
 | 
						|
 | 
						|
Building tools for Windows
 | 
						|
--------------------------
 | 
						|
If you wish to generate Windows versions of the utilities in the tools directory
 | 
						|
you can use MSYS2, a software distro and building platform for Windows.
 | 
						|
 | 
						|
Download the MSYS2 installer from https://www.msys2.org. Make sure you have
 | 
						|
installed all required packages below in order to build these host tools::
 | 
						|
 | 
						|
   * gcc (9.1.0)
 | 
						|
   * make (4.2.1)
 | 
						|
   * bison (3.4.2)
 | 
						|
   * diffutils (3.7)
 | 
						|
   * openssl-devel (1.1.1.d)
 | 
						|
 | 
						|
Note the version numbers in these parentheses above are the package versions
 | 
						|
at the time being when writing this document. The MSYS2 installer tested is
 | 
						|
http://repo.msys2.org/distrib/x86_64/msys2-x86_64-20190524.exe.
 | 
						|
 | 
						|
There are 3 MSYS subsystems installed: MSYS2, MinGW32 and MinGW64. Each
 | 
						|
subsystem provides an environment to build Windows applications. The MSYS2
 | 
						|
environment is for building POSIX compliant software on Windows using an
 | 
						|
emulation layer. The MinGW32/64 subsystems are for building native Windows
 | 
						|
applications using a linux toolchain (gcc, bash, etc), targeting respectively
 | 
						|
32 and 64 bit Windows.
 | 
						|
 | 
						|
Launch the MSYS2 shell of the MSYS2 environment, and do the following::
 | 
						|
 | 
						|
   $ make tools-only_defconfig
 | 
						|
   $ make tools-only
 | 
						|
 | 
						|
 | 
						|
Building without Python
 | 
						|
-----------------------
 | 
						|
 | 
						|
The tools-only builds bytes pylibfdt by default. To disable this, use the
 | 
						|
NO_PYTHON variable::
 | 
						|
 | 
						|
   NO_PYTHON=1 make tools-only_defconfig tools-only
 |
