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.
