MIPS: fix build on non-linux hosts
calc_vmlinuz_load_addr.c requires SZ_64K to be defined for alignment
purposes. It included "../../../../include/linux/sizes.h" to define
that size, however "sizes.h" tries to include <linux/const.h> which
assumes linux system headers. These may not exist eg. the following
error was encountered when building Linux for OpenWrt under macOS:
In file included from arch/mips/boot/compressed/calc_vmlinuz_load_addr.c:16:
arch/mips/boot/compressed/../../../../include/linux/sizes.h:11:10: fatal error: 'linux/const.h' file not found
^~~~~~~~~~
Change makefile to force building on local linux headers instead of
system headers. Also change eye-watering relative reference in include
file spec.
Thanks to Jo-Philip Wich & Petr Štetiar for assistance in tracking this
down & fixing.
