Building RPM for PPC (32 or 64 bits) I get

[  187s] cat syminfo.lst | sort | gawk -f ../../grub-core/genmoddep.awk > 
moddep.lst || (rm -f moddep.lst; exit 1)
[  187s] __ashldi3 in affs is not defined
[  187s] _restgpr_14_x in affs is not defined
[  187s] _restgpr_20_x in affs is not defined
[  187s] _restgpr_25_x in affs is not defined
[  187s] _restgpr_27_x in affs is not defined
[  187s] _restgpr_28_x in affs is not defined
[  187s] _restgpr_30_x in affs is not defined
...

for a long list of them.

Full build logs are available as

I do not myself have access to any PPC system nor any experience with
them.

x86 builds OK.
