I can see the problem in gotest. It has to do with the setting of GOARCH.
Previously GOARCH was being set based on the --goarch argument, but now
goarch is being set. Not sure both GOARCH and goarch are needed?
I've attached a patch I used to get it to work. It worked for ppc64le
and ppc64
with 64 and 32 bit.

The messages say this:

I don't know that I have access to a big-endian PPC GNU/Linux machine any more.
My first guess would be that somehow this case in libgo/testsuite/gotest
text="T"
case "$GOARCH" in
ppc64*) text="[TD]" ;;
esac
is not triggering. Although it checks for ppc64*, I think it's only
required on PPC64 ABI v1 (big-endian) and is not required for ABI v2
(little endian).
You could try changing to GOARCH there to goarch to see if it helps,
although as far as I can see either should work.
Otherwise, cd to the libgo working directory, run "make bufio/check",
figure out how it is running gotest, and run "bash -xv
gotest_invocation" and send it here.
