[PATCH] build: allow ./bootstrap --srcdir=... to work with a git submodule

[Jim Meyering]

When using git-bisect to see exactly when pr -oN broke,
I was dismayed to see that I couldn't easily build some older
versions from git due to their dependency on older versions
of gnulib.  Of course, this isn't at all surprising, once you
think about it, and I've been remiss for not doing this sooner...

So I'm about to make gnulib a "git submodule" of coreutils.

However, first, there's a small portability problem in the bootstrap
script that makes --scrdir=... fail to run module init with versions
of git newer than the one mentioned in the log below.

I confess I haven't tried this with an older version of git (I don't
even have an old enough version installed), so if someone can confirm
bootstrap --srcdir=... succeeds and a subsequent "git submodule status"
prints something, I'd appreciate it.

* bootstrap (git_modules_config): Use GIT_CONFIG, not GIT_CONFIG_LOCAL.
The latter was removed in v1.5.6.1-109-gdc87183.
