[poky] kernel module development problem with SDK

[György Kövesdi]

Hi,

I have poky at git hash 5686f4e1fe5229705b8c7d35895aa03827796d13 and I 
build for ARMv7.

I wanted to build my kernel module using the SDK generated this way:

     bitbake <my-image> -c populate_sdk

and the recipe kernel-devsrc is added to my sdk.

I found that the recipe meta/recipes-kernel/linux/kernel-devsrc.bb puts 
everything in the kernel source tree, except the following executables:

     scripts/recordmcount
     scripts/basic/fixdep
     scripts/mod/modpost

These would be essential for module development.

In the recipe kernel-devsrc.bb the following line

     oe_runmake -C $kerneldir CC="${KERNEL_CC}" LD="${KERNEL_LD}" clean 
_mrproper_scripts

removes everything, including the executables mentioned above.
IMHO it would be enough to run:

     oe_runmake -C $kerneldir CC="${KERNEL_CC}" LD="${KERNEL_LD}" clean

In this case the module development works properly with the resulting SDK.
Is the 'mrproper' really necessary? IMHO the 'clean' is enough there, 
because 'mrproper' removes too much.
