There were some changes recently [0] that means you should now use
'make-avr-toolchain', a procedure, in your manifest to have an
avr-toolchain package.

It was tested working, at least in clean environments (there's a current
caveat with toolchains where you can't use multiple of them in a same
profile in case that's what you were trying to do).

[0] see commit 35c1df5bd6317b1cd038c1a4aca1c7e4a52d4d93
