bootstrap broken

The current bootstrap of CVS head is broken:

bootstrap: fetching modules for src directory
bootstrap: copying file `src/getopt_.h'
cp: cannot stat `/usr/local/bin/lib/getopt_.h': No such file or directory

I traced it to this line in bootstrap:
gnulibdir=`which gnulib-tool | $SED "$dirname"`

First, it is looking for gnulib-tool on the path, instead of $GNULIB_TOOL.  
Second, since CVS gnulib does not have a `make install' to install gnulib-tool 
in any reasonable manner, my setup is that $HOME/gnulib contains the CVS 
snapshot, and /usr/local/bin/gnulib-tool is just a symlink to 
$HOME/gnulib/gnulib-tool, so that I did not have to edit my $PATH.  But that 
means that $gnulibdir in bootstrap is not pointing to the actual gnulib 
repository, just the directory where my symlink lives, explaining the failed cp.

Maybe I should also send a feature request to the gnulib tool, asking for a 
`configure; make; make install' feature that installs gnulib-tool on the path, 
and a `gnulib-tool --location' or something like that to allow scripts to learn 
where gnulib-tool is grabbing its files.

This patch allowed bootstrap to complete:
