Actually since those are pure rebuilds of RHSCL content, we should use 
-rh as <releasename>, so it will be rather sig-sclo7-devtoolset-3-rh.

Some further information how I suppose we can continue with rebuilding, 
which can also serve as a basic how-to for anybody who would like to 
help with rebuilding collections:

1) become SCLo sig member if you are not yet
http://wiki.centos.org/SpecialInterestGroup/SCLo#head-b6cbebda05530f216acf06e14f8c473a01750ed9

2) get srpm from software collections (list of repositories attached)
e.g. repoquery 
--repofrompath=r,https://www.softwarecollections.org/repos/rhscl/maven30/epel-7-x86_64 
--repoid=r maven30-cglib --arch src --location

3) during bootstraping we should use 0.x.<original_release> as Release 
in RPM, so we don't produce newer packages than the original NVRs are (1)

4) import the spec/patches into dist-git

5) create srpm from dist-git
e.g. by using fedora look-aside cache: fedpkg --dist .rpmbuild -bs 
--define "scl devtoolset-3" --define 'dist .el7' ~/rpmbuild/SPECS/gcc.spec

6) build the package in cbs.centos.org
koji -c /etc/koji.conf.d/cbs-koji.conf add-pkg 
sclo7-devtoolset-3-rh-candidate --owner=sclo devtoolset-3-memstomp
koji -c /etc/koji.conf.d/cbs-koji.conf build sclo7-devtoolset-3-rh-el7 
/home/hhorak/rpmbuild/SRPMS/devtoolset-3-memstomp-0.1.5-0.2.el7.src.rpm

My /etc/koji.conf.d/cbs-koji.conf also attached.

(1) cbs.centos.org doesn't allow to build one package twice with the 
same NVR. RHSCL product and softwarecollections.org packages already use 
some NVR. Since we bootstrap the collections, we don't want to produce 
newer packages (higher NVR) then what is already provided in RHSCL 
product and softwarecollections.org. Therefore I think we need to use 
0.x.<original_release> as Release in RPMs we will rebuild, where x is 
just increasing integer. Once we're sure the package is being built 
properly, we can use the original Release number.

Not all above was tested yet. I'll probably do some real work next week, 
but wanted to share the desired steps if anybody has some ideas or see 
some issues in the above.
