What do you mean? openSUSE:Factory:PowerPC/grub2 does not exist because
openSUSE:Factory:PowerPC links to openSUSE:Factory and pulls everything

- Enable grub2 for PowerPC LE (ppc64le)
- Add ppc64le to exclusive arches
- Don't require gcc-32bit (PowerLE don't have 32bit toolchain)

- added patches:
  * grub2-powerpc-libgcc.patch
     Provide 32bit libgcc functions for PowerLE

  * grub2-ppc64le-core-bigendian.patch
     Build grub kernel and images as BE on ppc64le (BL is BE there)

  * grub2-ppc64le-platform.patch
     Enable ppc64le platform
