How to use this variable, I tried following but kernel modules are still in same
place:
- make RTE_KERNELDIR_OUT=/tmp/kmod O=ferruh DESTDIR=/tmp/ferruh
- make RTE_KERNELDIR_OUT=/tmp/kmod O=ferruh DESTDIR=/tmp/ferruh install
- make RTE_KERNELDIR_OUT=/tmp/kmod O=ferruh DESTDIR=/tmp/ferruh modules_install
/tmp/kmod not created.
And what we are fixing here, what was wrong with old code?

${RTE_KERNELDIR} is used as external Linux kernel source folder, why we are want
to put artifacts into kernel source?
