Add SUSE vendor

[ismail]

Summary

SUSE's ARM triples end with -gnueabi even though they are hard-float. This requires special handling of SUSE ARM triples. Hence we need a way to differentiate the SUSE as vendor. This CL adds that.

We have some unit tests for Triple. Can you add some, pls?

Add test

LGTM. Thanks!
