+Currently gzip on host is used. If host gzip is provided by pigz, it fails to
+redo install that pigz can't handle the option after file name. When run:
+
+gzip src/backfire/backfire.4 -c > OUTPUT_FILE
+
+File src/backfire/backfire.4 is zipped into backfire.4.gz but the OUTPUT_FILE
+is empty. When rerun do_install, it shows warning:
+
+| gzip: src/backfire/backfire.4 does not exist -- skipping
+
+and empty manual gzip files are created:
+
+$ file image/usr/share/man/man4/backfire.4.gz
+image/usr/share/man/man4/backfire.4.gz: empty
+
+Fix it by putting option '-c' before the file name.
