Cross-compiling a kernel snap using snapcraft in edge channel fails. Installing the one in the stable channel works though. This is in artful.

Cannot find the linker to use for the target base 'core'.
Please verify that the linker exists at the expected path '/snap/core/current/lib/ld-linux-armhf.so.3' and try again. If the linker does not exist contact the author of the base (run `snap info core` to get information for this base).

Snapcraft aims to make upstream developers' lives easier and as such is not a
