 Hi Christopher,

 Thank you for your patch. However, you have not followed the patch submission
guidelines [1] which makes the patch harder to review. I'll indicate a few
points here, but there will probably be more.

 The patch title should be:

busybox: add conditional dependency on libselinux


 The explanation you give in your mail above should be put in the commit message.


 The comment you added is a bit long, perhaps:

# The user may select the selinux support applets.
# We'll assume he's smart enough to select libselinux in that case.
ifeq ($(BR2_PACKAGE_LIBSELINUX),y)
BUSYBOX_DEPENDENCIES += libselinux
BUSYBOX_LDFLAGS += -lselinux
endif


 Regards,
 Arnout
