Buildid displays or updates the build ID stored in a Go package or binary.

Usage:

	go tool buildid [-w] file

By default, buildid prints the build ID found in the named file.
If the -w option is given, buildid rewrites the build ID found in
the file to accurately record a content hash of the file.
