[bitbake-devel] [PATCH v4 07/18] fetch2/git.py: Use local download dir, when using an external read-only GITDIR

[Jason Wessel]

When building the yocto kernel or yocto kernel tools, if the GITDIR is
on a read-only server that is shared and updated by via some cron
jobs, the fetch2 should not try to write to that area.  The end result
will be odd failures if you have download turned off, or extra
needless downloading if you have download turned on.

The fetch2 should prefer to create mirror the mirror clones in the
local "downloads" directory in the work space.
