When running do_package_write_deb, we have trees of hardlinked files
such as the dbg source files in ${PN}-dbg. If something makes another
copy of one of those files (or deletes one), the number of links a file
has changes and tar can notice this, e.g.:
| DEBUG: Executing python function do_package_deb
| dpkg-deb: building package `sed-ptest' in `/media/build1/poky/build/tmp/work/i586-poky-linux/sed/4.2.2-r0/deploy-debs/i586/sed-ptest_4.2.2-r0.3_i386.deb'.
| tar: ./usr/lib/sed/ptest/testsuite/tst-regex2: file changed as we read it
| dpkg-deb: error: subprocess tar -cf returned error exit status 1
Tar returns an error of 1 when files 'change' and other errors codes
in other error cases. We tweak dpkg-deb here so that it ignores an exit
code of 1 from tar. The files don't really change (and we have locking in
place to avoid that kind of issue).
