bitbake: fetch2: fix fetching git submodules with git 1.7.9.x or older
Git versions older than 1.7.10 put absolute paths in configuration files for the submodule repositories, leading to errors when the repository checkout is moved. We move the repository as a matter of course in the gitsm fetcher; the failure occurs in do_unpack). Change the absolute paths to be relative during processing to fix this. (At the time of writing, Ubuntu 12.04.4 LTS ships Git version 1.7.9.5, hence the desire to fix this rather than just mandating a newer Git version.) Fixes [YOCTO #5525]. (Bitbake rev: e700d5a41deed4ee837465af526ed30c8a579933) Signed-off-by: Paul Eggleton <paul.eggleton@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
