I think we should just onramp into the AltArch SIG, and use the
mechanics already coming up in place there.

This issue further prevents the use of Fedora 21 LE rpms because they all require GLIBC_2.18 and c7 provides GLIBC_2.17.

We should have basic VM's up that can be used soon, and we have some
resources at OSL that can be made available for wider community side
participation on the platform, once we have enough of the distro
bootstrapped. I know a few other SIG's have expressed interest in being
able to build on power as well, we should be able to provide that
capability soon after we have the baseline bootstrap up.

thanks James,
