Sorry, I guess I'm just slow, because I don't quite follow.  If you
make that change to the source code, and then use --avoid, the file
"unlocked-io.h" be missing.  So you need your own substitute
unlocked-io.h, which (presumably) does nothing.  I guess this will work,
but should we instead be striving for an approach where gnulib arranges
for the no-op unlocked-io.h?  That would be more convenient.

This doesn't look quite right to me.  xalloc-die depends on error,
gettext-h, and exitfail, because its implementation uses those three
modules.  But a user who substitutes a specially-built xalloc-die
implementation may not need those three modules.  It's common to take
the transitive closure of the dependencies to see which modules your
app needs.  In that scenario, user would end up with modules like
"error" that they don't need.
