Ticket 48824 - Cleanup rpm.mk and 389 specfile
    
    Description:  Removed the jeamlloc bundling code.
                  Set a version requirement for srvcore.
                  Set ASAN to off by default.
                  Removed incorrect comparison:  %if %0{?VAR:1}  which only
                   checks if the VAR is defined, not what it is set to.  So
                   those checks always returned true, even if the VAR was set
                   to 0.
