[OE-core] [PATCH] gcc-runtime: Add multilib C++ header mapping

[Richard Purdie]

The SDK was unable to find the C++ header pieces correctly since its
using a generic compiler, not one specifically targeting the multilib
vendor prefix. This adds in the right mapping to ensure multilib SDKs
work as expected. This fixes multilib SDK automated tests.
