Sure! That's what Open Source is for! :-)

Ok, I will remove it.

This line is also present on LINUX_BUILD_CMDS, any reason not to reuse it?
LINUX_BUILD_CMDS does a couple of more things than what is done here,
like like running LINUX_BUILD_DTB or 'make modules', and maybe that is
not wanted?

Ok, just wondering, why? I mean, IIUC, LINUX_INSTALL_IMAGES_CMDS also
handles the DTB copy when APPENDED_DTB is not set, right?
