--disable-utilities causes test failure

[WardF]

As originally reported in issue EDB-648764

---

In netcdf-C 4.4.1, the autotools configure option --disable-utilities
causes this make check failure:

FAIL: run_diskless.sh

nc_test/run_diskless.sh.log says:

./run_diskless.sh: line 103: ../ncdump/ncdump: No such file or directory
FAIL run_diskless.sh (exit status: 1)

This is an extremely minor problem of course, but I thought I should report
it. It seems to me that one of these remedies should be added:

1. Guard this test and others like it, so they do not fail on missing
   utilities.
2. Add a comment in the options documentation next to --disable-utilities,
   something to the effect of "Utilities must remain enabled for normal
   operation of the test suite".

Please add one of these at your convenience, or let me know if there is
something better. Thanks.

When -DENABLE_UTILITIES=OFF is passed in a cmake-based build multiple tests fail:

 17 - nc_test_run_diskless (Failed)
 18 - nc_test4_run_grp_rename (Failed)
 20 - nc_test4_tst_misc (Failed)
 54 - nc_test4_tst_xplatform (Failed)
110 - ncdap_tst_remote3 (Failed)
111 - ncdap_tst_formatx (Failed)

I suspect they also need to be fenceposted.

Turns out the other tests happen in autotools-based tests as well, they just aren't reached because make check bails before they are run.

Resolved.
