[OE-core] [PATCH 0/2] Use alternatives for all of binutils instead of -symlinks

[Saul Wold]

During MUT builds, we saw a failure with the toolchain


| Computing transaction...error: Can't install 
binutils-cross-canadian-arm-2.23.2-r4 at i686_nativesdk: no package 
provides update-alternatives-cworth
|

Can be seen all architectures.


Sau!
