opkg: update-alternatives fails for "[" and "[[" in busybox

Building a small filesystem with busybox gives the following error lines:
(see log.do_rootfs under bitbake_build/tmp/work/)
sed: -e expression #1, char 41: unterminated address regex
sed: -e expression #1, char 42: unterminated address regex This is caused by the script bitbake_build/tmp/sysroots/x86_64-linux/usr/bin/update-alternatives. "[" can not be used directly in sed expression.

update-alternatives is now provided by the opkg-utils recipe, not opkg. opkg-utils is part of the Yocto Project so we maintain upstream as well. Could you take a look at the contribution guidelines for opkg-utils (http://git.yoctoproject.org/cgit/cgit.cgi/opkg-utils/tree/CONTRIBUTING)
and submit the patch against that? We can then just bump the SRCREV which is used within OpenEmbedded, rather than maintaining an isolated patch.

This should hopefully be fairly straightforward to do, the patch you have should apply cleanly to update-alternatives (there is no 'update-alternatives.in' anymore) and then just commit and send to the appropriate email addresses. If there's any issues let me know.

When opkg v0.3.0 is released, it will no longer contain the update-alternatives script so hopefully that will make things less confusing.

Thanks,

Paul Barker
