[OE-core] [RFC] don't run make clean on kernel_do_install

[Koen Kooi]

Hi,

Over the holidays I was trying to build some externel kernel modules and they failed to build because linux/bounds.h wasn't in sysroots.

I did this quick hack to work around it:

--- a/meta-oe/classes/kernel.bbclass
+++ b/meta-oe/classes/kernel.bbclass
@@ -159,7 +159,8 @@ kernel_do_install() {
        # we clean the scripts dir while leaving the generated config
        # and include files.
        #
-       oe_runmake -C $kerneldir CC="${KERNEL_CC}" LD="${KERNEL_LD}" clean
+       find $kerneldir -name "*.o" -delete
+       #oe_runmake -C $kerneldir CC="${KERNEL_CC}" LD="${KERNEL_LD}" clean
        make -C $kerneldir _mrproper_scripts
        find $kerneldir -path $kerneldir/scripts -prune -o -name "*.[csS]" -exec rm '{}' \;
        find $kerneldir/Documentation -name "*.txt" -exec rm '{}' \;

I'm not convinced that the above is the right way to solve it, but I lack the required kbuild knowledge to come up with a better one. Does anyone have a hint on how to approach this problem in a better way?

regards,

Koen
