Have you tried using ./autogen.sh instead of ./bootstrap?  While
./bootstrap is part of the process for building a git checkout, it is
not the entire process, and we document that you should be using
./autogen.sh.  I don't have much experience with using --no-git, but I'd
like to fix the problem if I can reproduce it.

The problem may lie in upstream gnulib's bootstrap script; if so, the
problem won't be fixed until our next gnulib submodule update, which
will be after 1.1.0 is released.

As for a workaround - if you don't have git access on your devel
machine, then I suggest that you get another machine that DOES have git
access, and use that machine to get sources and build tarballs, then
copy tarballs to the machine where you are trying to run tests.  That
is, your setup of trying to develop code on a machine that can't access
outside a firewall is unusual, so it may require more effort on your
part to get working.  Also, how strict is your firewall?  Is it a case
where you can access upstream via http:// but not git://?  If so, it is
possible to modify your ~/.gitconfig to tell git to rewrite git URIs to
pull from locations that are accessible through your firewall; but
again, this may be something where you have to do a bit of research
yourself.
