THe stdio subdir is actually required by the documentation. The stdio/def is handled dynamically, but libc.texi always expects it to be included, and fails if it isn't. So making it required when building docs is safe. The xdr subdir is handled dynamically, but it doesn't include any docs, so the dynamic logic isn't (currently) adding any value. So making it required when building docs is safe. That leaves: iconv, stdio64, posix, and signal subdirs. The chapters have a little disclaimer saying they are system-dependent, but even then, imo having stable manuals regardless of the target is preferable, and we can add more disclaimer language to these chapters if we want. This doesn't touch the man page codepaths, just the info/pdf.
