RFC: turn off ppc32 and ppc64 big endian builds on openSUSE:Factory:PowerPC

Hi all, recently I was made aware that openSUSE:Factory:PowerPC is quite a large distribution as it is building for ppc 32bit, ppc64 big endian and ppc64 little endian. in OpenQA as far as I know we are only testing the ppc64 little endian builds. Given the upcoming data center move and the lack of testing, are there any concerns about turning off the builds for ppc 32bit and ppc64 big endian? It would reduce build power needs as well as disk storage /publishing bandwidth which is shared with other distributions and architectures and becomes a problem because of PowerPC being exceptionally large. Thanks a lot in advance for any insight you can provide, Greetings, Dirk
