Subject: luci.mk: fix branch detection in detached HEAD state
X-Git-Url: http://git.archive.openwrt.org/?p=project%2Fluci.git;a=commitdiff_plain;h=05c5924434786c6720e0a497215fce0337d57d82

luci.mk: fix branch detection in detached HEAD state

When LuCI is checked out via pinned feeds configuration, its source tree will
end up in detached head state, requiring some more magic to figure out the
proper branch.
