This would be one possibility.  You could have a with
  cmp "$srcdir/"

and list shell_script in as
  AC_CONFIG_FILES([shell_script], [chmod a+x shell_script])

But this is probably even overkill.  You could just export a shell
variable containing srcdir from Makefile to the script -- no need to
construct that at all, then:  If, for example, you use the Automake test
feature, as in
  TESTS = shell_script ...
  check_SCRIPTS = ...
  check_PROGRAMS = ...

then you could just add
  TESTS_ENVIRONMENT = srcdir="$(srcdir)" ...

and use "$srcdir" within the script.  Or, if you have many scripts that
share some initialization, you could just substitute this initialization
part and source that from all shell scripts (by `. ./defs', for example).

Yep.  Examples for test suites are contained in (sorry for the shameless
  Automake test suite:  Automake, Libtool-1.5.x
  Autotest test suite:  Autoconf, Libtool-CVS
  DejaGNU  test suite:  GCC
