[PATCH] BaseTools:build break if the Path contains SingleFile.Ext

["Fan, ZhijuX" <zhijux.fan@intel.com>]

BZ:https://bugzilla.tianocore.org/show_bug.cgi?id=1325

if SingleFile.Path = "/foo/bar.Sap/yada/source.S" and 
SingleFile.Ext = ".S". Then key would end up "/foo/bar"
instead of "/foo/bar.Sap/yada/source" as intended.
