- please remove the scl macros, they are not needed for fedora
- remove group: this is only needed if you intend building for epel5
- remove BuildRoot: this is only needed if you intend building for epel5
- remove defattr, this is not needed anymore
- add ExclusiveArch: %{nodejs_arches} noarch for fedora > 19
