For all of those modules, gnulib-tool knows they require lib/xalloc.h,
yet for xvasprintf, it does not, due to the missing dependency.
The xvasprintf module description should indicate that it needs xalloc.h,
one way or another.  Depending on xalloc-die is one way to do that.
An alternative is to add lib/xalloc.h to the Files: section.
