[PATCH] kernel.bbclass: fix external module building

[PATCH] kernel.bbclass: fix external module building

[Khem Raj]

From: Denis Carikli <GNUtoo@no-log.org>

Without that fix we have the following while compiling compat-wireless.
  include/linux/mmzone.h:18:30: fatal error: generated/bounds.h: No such file or directory

Note that the compat-wireless recipe will be added in another commit.

Hrm... I'm not clear on why this is necessary. I understand why you need
bounds.h... but I don't see why it isn't there already.

A few lines up we do:

cp -fR * $kerneldir

Which should cover include/generated/bounds.h...

Perhaps "make -C $kerneldir _mrproper_scripts" clears that out... Ah,
yes, that seems to be the case. Grumble.

OK,

Having established why this is needed, could the commit message and/or comment 
clearly state the reason so that there's something to refer to in future?

Thanks,
Paul
