Description of problem:
Dependency to libselinux(-devel) even if SELinux is disabled at 
rebuilding time:

--- snipp ---
# rpmbuild -ba shadow-utils.spec
error: Failed build dependencies:
        libselinux-devel is needed by shadow-utils-4.0.3-25
#
--- snapp ---

Version-Release number of selected component (if applicable):
shadow-utils-4.0.3-24

How reproducible:
Everytime, see below.

Steps to Reproduce:
1. Set "%define WITH_SELINUX 0"
2. rpmbuild -ba shadow-utils.spec
3. Get the dependency error
  
Actual results:
Dependency to libselinux(-devel) even if SELinux is disabled.

Expected results:
Dependency to libselinux(-devel) only if SELinux is enabled; the 
following change solves it for me:
