Subject: [PATCH] feat: add go:linkname directives for defaultToolTags and
 defaultReleaseTags
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add linkname directives and stdlib comments for defaultToolTags and
defaultReleaseTags variables to match Go standard library pattern. This
allows external packages (like gopherjs) to access these internal variables
via linkname, maintaining compatibility with packages that depend on this
behavior.
