Subject: kernel.bbclass: do not mv/link sources when externalsrc enabled
X-Git-Tag: 2015-10~509

kernel.bbclass: do not mv/link sources when externalsrc enabled

If externalsrc is enabled the 'do_unpack' task is run if the recipe has
some local source files. In the case of kernel recipe this caused the
(externalsrc) source tree to be moved/symlinked. This patch prevents the
behaviour, making sure the source tree is not moved around when
externalsrc is enabled. Instead of moving the source tree,
STAGING_KERNEL_DIR will be a symlink to it.
