+ * Linux kernel build uses gzip -d -n. We accept and ignore it.
+ * Man page says:
+ * -n --no-name
+ * gzip: do not save the original file name and time stamp.
+ * (The original name is always saved if the name had to be truncated.)
+ * gunzip: do not restore the original file name/time even if present
+ * (remove only the gzip suffix from the compressed file name).
+ * This option is the default when decompressing.
+ * -N --name
+ * gzip: always save the original file name and time stamp (this is the default)
+ * gunzip: restore the original file name and time stamp if present.
