…ld (NOAA-EMC#219)

* Set correct no bounds check for Intel and gfortran and only for Debug build.

Older versions of gfortran don't accept "-fcheck=no-bounds" but do accept
"-fno-bounds-check" even though the later form is deprecated.

* Use foreach loop.

* Changed use of the new format for -fcheck to gfortran >= 6.
