Subject:    [OE-core] [PATCH] gcc: Fix riscv multilibs for OE way

[Download RAW message or body]

In OE we do not build mutlib like gcc does it by default, this ensures
that mutlilib is virtually disabled for OE, since we hardly use same gcc
to build for multiple ABIs

This fixes cases in SDK where g++ is not able to find standard c++
include headers
