Bug 1749508

Description of problem:
There is a fragment of the RPM spec file below which includes a bad logical check on the RHEL-7 architecture for including spatialite dependency. Spatialite is not available on ppc64 but the logic excludes its use except for ppc64.

Version-Release number of selected component (if applicable):
gdal-1.11.4-3

How reproducible:
Consistently

Steps to Reproduce:
1. Observe the runtime dependencies of the gdal packages don't include libspatialite.
2. Attempt to use spatialite within application using GDAL (including ogr2ogr) and observe failure.

Actual results:
Cannot use spatialite extensions.

Expected results:
Should be able to use spatialite.

Additional info:

Current spec file fragment:
# No ppc64 build for spatialite in EL7                                                                                                                                       
# https://bugzilla.redhat.com/show_bug.cgi?id=663938                                                                                                                         
%if 0%{?rhel} == 7
%ifnarch ppc64
%global with_spatialite 0
%global spatialite "--without-spatialite"
%endif
%endif

Should instead include the line:
%ifarch ppc64
