Errors compiling on Raspberry Pi

[mozcelikors]

I am getting the following compile error, trying this on a raspberry pi 3 (which should also work).

| /bin/sh: 1: arm-poky-linux-gnueabi-gcc  -mno-thumb-interwork -marm -fuse-ld=bfd -fdebug-prefix-map=/home/mozcelikors/poky/build/tmp/work/raspberrypi3-poky-linux-gnueabi/fbtft-driver/1.0-r0=/usr/src/debug/fbtft-driver/1.0-r0 -fdebug-prefix-map=/home/mozcelikors/poky/build/tmp/work/raspberrypi3-poky-linux-gnueabi/fbtft-driver/1.0-r0/recipe-sysroot-native= -fdebug-prefix-map=/home/mozcelikors/poky/build/tmp/work/raspberrypi3-poky-linux-gnueabi/fbtft-driver/1.0-r0/recipe-sysroot=  -fdebug-prefix-map=/home/mozcelikors/poky/build/tmp/work-shared/raspberrypi3/kernel-source=/usr/src/kernel: not found

Following lines are interesting: | /bin/sh: 1: arm-poky-linux-gnueabi-gcc -mno-thumb-interwork -marm -fuse-ld=bfd -fdebug-prefix-map=/home/mozcelikors/poky/build/tmp/work/raspberrypi3-poky-linux-gnueabi/fbtft-driver/1.0-r0=/usr/src/debug/fbtft-driver/1.0-r0 -fdebug-prefix-map=/home/mozcelikors/poky/build/tmp/work/raspberrypi3-poky-linux-gnueabi/fbtft-driver/1.0-r0/recipe-sysroot-native= -fdebug-prefix-map=/home/mozcelikors/poky/build/tmp/work/raspberrypi3-poky-linux-gnueabi/fbtft-driver/1.0-r0/recipe-sysroot= -fdebug-prefix-map=/home/mozcelikors/poky/build/tmp/work-shared/raspberrypi3/kernel-source=/usr/src/kernel: not found

Which I believe is related to the following portion of the recipe:

do_compile() {
  unset CFLAGS CPPFLAGS CXXFLAGS LDFLAGS CC LD CPP
  oe_runmake 'MODPATH="${D}${base_libdir}/modules/${KERNEL_VERSION}/kernel/drivers/video/fbt$
             'KDIR="${STAGING_KERNEL_DIR}"' \
             'KERNEL_VERSION="${KERNEL_VERSION}"' \
             'CC="${KERNEL_CC}"' \
             'LD="${KERNEL_LD}"'
}

My suspection is that since this is done with the kernel space compiler, I might be missing possible unspecified dependencies. Also the error involves a host side directory /usr/src/kernel which is empty. I am curious what that is.

NOTE: For providing the virtual/kernel, I am using linux-raspberrypi-1_4.14 package.

Any help is appreciated.
