import-layers/yocto-poky/meta/recipes-devtools/opkg-utils/opkg-utils/tar_ignore_error.patch

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:

| DEBUG: Executing python function do_package_ipk
| tar: ./usr/src/debug/gperf/3.0.4-r0/gperf-3.0.4/src/main.cc: file changed as we read it
NOTE: recipe gperf-3.0.4-r0: task do_package_write_ipk: Failed
ERROR: Task 6539 (recipes-extended/gperf/gperf_3.0.4.bb, do_package_write_ipk) failed with exit code '1'


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:
