Paul Spooren 4ed356fa71 kernel.mk: add KCFLAGS to make kmods reproducible
Some kmods (gpio-hotplug, wireguard) store the build path in the
compiled files and therefore make it harder to rebuild the official
binaries. As the same "iremap" function is used as for other binaries,
the change is compatible with gcc7 and 8.

Tested with both gcc7 and gcc8 resulting in build path independent
reproducible builds.

 -----------------------------------------------------

This is the buildsystem for the OpenWrt Linux distribution.

To build your own firmware you need a Linux, BSD or MacOSX system (case
sensitive filesystem required). Cygwin is unsupported because of the lack
of a case sensitive file system.

You need gcc, binutils, bzip2, flex, python3.5+, perl, make, find, grep, diff,
unzip, gawk, getopt, subversion, libz-dev and libc headers installed.

1. Run "./scripts/feeds update -a" to obtain all the latest package definitions
defined in feeds.conf / feeds.conf.default

2. Run "./scripts/feeds install -a" to install symlinks for all obtained
packages into package/feeds/

3. Run "make menuconfig" to select your preferred configuration for the
toolchain, target system & firmware packages.

4. Run "make" to build your firmware. This will download all sources, build
the cross-compile toolchain and then cross-compile the Linux kernel & all
chosen applications for your target system.
