Commit 10b63956fce7f369cc37fd4d994f09bd5203efe4 which plumbed in UAPI
broke the destination-y functionality of scripts/Makefile.headersinst.

The variable destination-y is used in a := assignment and so is expanded at
declaration time, and the include of the Kbuild fragments that set
destination-y to something is after this time, so it now always expands empty.

There are no in-tree users of destination-y, but it allows any
Kbuild-fragment to redirect where headers are installed.

Just move the assignment of the variable that uses it below the include
of the Kbuild fragment.

I applied your patch to kbuild.git#kbuild, but please send -p1 patches
