When an architecture has a set of exported headers that needs to be
exported to a different directory destination-y is used.
destination-y specifies the destination directory for all exported
headers in the file where it is present.
Example:
#arch/xtensa/platforms/s6105/include/platform/Kbuild
destination-y := include/linux
In the example above all exported headers in the Kbuild file
will be located in the directory "include/linux" when exported.
