Fixed, hope it's correct this time. Sent as -v4.

I need LINUX_BACKPORTS_MAKE_ENV, as KLIB and KLIB_BUILD aren't set.

Unfortunately it has to be build this way (or I haven't found any better).
LINUX_BACKPORTS_BUILD_CMDS needs -C $(@D), otherwise there is infinite loop. I'm
surprised, as $(@D) is backport directory (I'd expect to be add automatically) - suppose I
have an error somewhere.
LINUX_BACKPORTS_INSTALL_TARGET_CMDS needs -C $(LINUX_DIR) M=$(@D)
=> different commands.

Taken from busybox where it wasn't (sent as separate patch). Added...
BTW: I'd expect to have one unique default variable for all of those.

Kind regards,
