[OE-core] [PATCH] kernel.bbclass: Don't include source files for "other" architectures in the sysroot

[Phil Blundell]

Since the sysroot is per-machine, we can be fairly confident that any
out-of-tree modules which look at our sources will be building for the
same architecture that we are.  This being the case there's no need to
ship the sources for any other architectures, which saves disk space and
time (about 30 seconds in do_package, in a somewhat unscientific test
with ARCH=mips).

Of course, an even better fix would be to not install these files in the
first place, but deleting them is easier.
