Subject: Fix warning about duplicate id in docbook XML

../newlib/libc/libc.xml:22242: element refentry: validity error : ID iconv already defined
    <refentry id="iconv">

Use a separate namespace for chaper ids, to avoid collision between the
ids for the chapter and function 'iconv', now that iconv documentation
is generated unconditionally.
