automake 1.12.x automatically deletes empty directories, so
the additional rmdir from the do_install_append fails.
cleanup the do_install_append for automake 1.12.x
avoid this issue:
| rmdir: failed to remove `/srv/home/nitin/builds/build-gcc47/tmp/work/i586-poky-linux/libgcrypt-1.5.0-r0/image/usr/sbin': No such file or directory
NOTE: package libgcrypt-1.5.0-r0: task do_install: Failed
no PR bump as no change in the output
