4.4-stable review patch. If anyone has any objections, please let me know.
------------------
[ Upstream commit 975f57fdff1d0eb9816806cabd27162a8a1a4038 ]
When calling ppc-xlate.pl, we pass it either linux-ppc64 or linux-ppc64le. The script however was expecting linux64le, a result of its OpenSSL origins. This means we aren't obeying the ppc64le ABIv2 rules.
Fix this by checking for linux-ppc64le.
