Edit StackMin (for the non-split-stack case) in libgo/runtime/proc.c and rebuild libgo. Note that GCC does support split stacks for 64-bit PPC.

It probably wouldn't be too hard for someone familiar with PPC32 and PPC64 as used on GNU/Linux. Basically look for every file in the Go distribution with "ppc64" in the name, and plan to write a plan "ppc" version.
