We do try mark scripts executable, but you may have been misled by the
fact that we then try to avoid _depending_ on that during the build.

That's mostly because some people still use old workflows with
patches, and the executable bit will be lost if you apply a patch
without the proper git tools.

(I think we've also had cases where people were developing on no-exec
filesystems etc).

So while we try to mark scripts executable, we then actually generally
execute them using an explicit interpreter invocation anyway (ie using

  $(CONFIG_SHELL) "some-script-path"

or similar).
