* configure.ac: Add option --enable-large-data-tests.
* tests/hashtest-256g.in: New.
* tests/Makefile.am (EXTRA_DIST): Add hashtest-256g.in.
(TESTS): Split up into tests_bin, tests_bin_last, tests_sh, and
tests_sh_last.
(tests_sh_last): Add hashtest-256g
(noinst_PROGRAMS): Add only tests_bin and tests_bin_last.
(bench-slope.log, hashtest-256g.log): New rules to enforce serial run.

     Here is a list of configure options which are sometimes useful
     for installation.
 
+     --enable-large-data-tests
+                     With this option a "make check" will take really
+                     long due to extra checks for the hash algorithms.

      --enable-m-guard
                      Enable the integrated malloc checking code. Please
                      note that this feature does not work on all CPUs
