I ran into that problem during ./bootstrap -- it seems gnulib-tool
relies on the 'join' tool as well:

./bootstrap: gnulib/gnulib-tool    --no-changelog   --aux-dir=build-aux   
--doc-base=doc   --lib=libgnu   --m4-base=m4/   --source-base=gl/   
--tests-base=gl/tests   --local-dir=gl      --libtool --import ...
gnulib/gnulib-tool: line 1: join: not found

The ./bootstrap script completes without error exit, but failed to setup
the build properly.

Do we want to support ./boostrap on systems without 'join'?

If not, I suggest the patch below.
