This reverts commit 243b50c141d71fcf7b88e94474b3b9269f0b1f9d.
When packaging the kernel it is built in different place from the one in
which it will be installed. After build the makefile needs to be
regenerated with the target location but with mkmakefile merged into
Makefile tehre is no way to do that.
