[PATCH] Set goarch to ppc64le where needed for gccgo testing

[Lynn A. Boger]

Hi,

This change goes along with the change to the GOARCH setting in gccgo 
for ppc64le which will be done in gofrontend.  The description for that 
change is here: 
https://groups.google.com/forum/#!topic/gofrontend-dev/ocEttrpsw-s

This change has been bootstrapped and tested along with the above change 
to gofrontend on ppc, ppc64, and ppc64le.
