[OE-core] [zeus 10/28] sanity: check the format of SDK_VENDOR

[Armin Kuster]

From: Ross Burton <ross.burton at intel.com>

If SDK_VENDOR isn't formatted as -foosdk and is instead for example -foo-sdk
then the triple that are constructed are not in fact triples, which results in
mysterious compile errors.

Check in sanity.bbclass so this failure is detected early.
