[bitbake-devel] [PATCH] bitbake: fetch2: try_mirror_url(): Replace old git with mirror

[Ernst Sjöstrand]

If we're trying to fetch a git, we're in try_mirror_url and
origud.localpath is a directory, that means the original clone is broken
for some reason but we found a mirror that works.
Remove the original clone and replace it with a symlink, like what would
hopefully be done on a fresh fetch.

[ Yocto # 13278 ]
