The Texinfo manual doesn't say that explicitly for anchors.  It does
say that for node names:

   * Unfortunately, you cannot use periods, commas, colons or
     parentheses within a node name; these confuse the Texinfo
     processors.

These limitations are due to the syntax of menus and cross-references
where these characters delimit syntactically significant parts of the
reference.

In the section about anchors, there's this text that hints that
anchors and nodes share the same limitations:

      Anchor names and node names may not conflict.  Anchors and nodes are
    given similar treatment in some ways; for example, the `goto-node'
    command in standalone Info takes either an anchor name or a node name as
    an argument.

I will ask the Texinfo maintainer to add an explicit text about anchor
name limitations.

How about "qXfer auxv read" or "qXfer read auxiliary vector"?

Well, at least in this hunk the text was not touched:

There are several commas missing in these two sentences.

Anyway, I've read all of your text yesterday, so it's okay with me.
