native tools must reliably use a native adjunct, even if that's inconvenient
While it is perhaps convenient for native tools to use updated versions
of certain things like libxml it is imperative that those versions are
_also_ build for the build machine.  Thus they need to be in the native
adjunct (even if that native adjunct is thus not /).
Fix the native adjunct to be rooted similarly to the adjunct proto (that
is, at /), and fix SMF to use it correctly
