[OE-core] [PATCH 1/1] opkg-build: Ignore tar error due to hardlinks issue when creating ipk files

[Alejandro Hernandez]

If a the number of hard links decreases or increases while creating
the tar files used for an ipk package, tar fails with error code 1,
if this is the case we ignore the error and continue to create the ipk file

+
+We detect if the error code produced by tar is 1 and in this case ignore it.
+
+This a similar behavior to the one on dpkg:
