           Summary: SRC_URI file:// symlink looses link name
           Product: Openembedded
           Version: org.openembedded.dev
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: P3
         Component: unspecified
        AssignedTo: openembedded-commits at lists.openembedded.org
        ReportedBy: jfaith7 at gmail.com


A recipe with a file:// SRC_URI which is a symbolic link to a directory is
copied in the temp dir during do_unpack as the link target, not the name of the
link itself.

For example:
Create a link with: ln -s a_dir link_to_a_dir

And put in the package recipe:
SRC_URI="file://link_to_a_dir"

The directory gets copied as "a_dir" and not "link_to_a_dir".

This seems to be caused by the line "local = os.path.realpath(local)" in
base_do_unpack() in classes/base.bbclass which will convert local to "a_dir". 
If the local var were passed unconverted into oe_unpack_file(), then it could
trim the path of the link before calling os.path.realpath() to preserve the
link name.
