grub2/grub2-powerpc-libgcc.patch
Michael Chang fce44a3b44 Accepting request 220504 from home:k0da:ppc 
- 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
