`bootstrap' fails with local gnulib dir

[git commit d69fa5284851b2b7aac25ffac638b6b379994db5]

Calling

  ./bootstrap --skip-git --gnulib-srcdir=/home/wl/git/gnulib

fails with

  bootstrap:   error: Can't find, copy or download 'build-aux/git-version-gen', a required
  bootstrap:          gnulib supplied file, please provide the location of a
  bootstrap:          complete 'gnulib' tree by setting 'gnulib_path' in your
  bootstrap:          'bootstrap.conf' or with the '--gnulib-srcdir' option -
  bootstrap:          or else specify the location of your 'git' binary by
  bootstrap:          setting 'GIT' in the environment so that a fresh
  bootstrap:          'gnulib' submodule can be cloned.

Reason: Due to

  gnulib_path=build-aux/gnulib

in file `bootstrap.conf' the function
`func_require_dotgitmodules_parameters' never checks
`$opt_gnulib_srcdir'.

Attached is an ad-hoc fix that worked for me.
