Subject: scripts/config: support includes relative to the currently processed file
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=2f39014a4843f801e6fdc2ebd77b5523cb38f4b3;p=openwrt%2Fstaging%2Fthess.git

scripts/config: support includes relative to the currently processed file

When the initial glob() attempt on a path specified with "source" statement
yields no result, then retry the globbing on the same path with the directory
part of the currently processed file prepended.

This allows us to reference Config.in files relative to their parent instead
of relative to the top dir.
