Allow Python packages to be dropped
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.
