[ptxdist] opkg: wget/curl dependencies

[Alexander Dahl]

Hei hei, 

while testing some things with wget I noticed it's possible to configure
ptxdist in a way opkg on the target get's useless. I can unset all of
BUSYBOX_WGET, WGET and OPKG_CURL so opkg can not fetch lists and
packages anymore. I played with the "select" statement of kconfig but
couldn't figure out a way to set a dependency like "any of those three
but at least one" (which is probably even more complicated because both
wget variants exclude each other). Is it possible to handle such
dependencies with kconfig and how?

Well, you can still install packages provided e.g. with a USB stick, or
something like that.

maybe something like this:

config OPKG_DOWNLOAD
	bool
	prompt "make sure opkg can download something"
	select WGET if RUNTIME && !OPKG_CURL && !BUSYBOX_WGET
