- Authentication-results: sourceware.org; auth=none
Hi,
Please backport this change to the gcc 4.9 branch so that the GOARCH
value setting for ppc64le is consistent with trunk.
This has been bootstrapped and regression tested on ppc64le and ppc64
(along with the other patches submitted for the
4.9 branch today).

* gcc/testsuite/go.test/go-test.exp: Recognize goarch value pp64le
* libgo/configure.ac: Set GOARCH ppc64le where appropriate
* libgo/go/go/build/syslist.go: Add ppc64le to the goarchList
* libgo/configure: regenerate
