First off, no need for apologies.  This is obviously quite an esoteric issue, 
and I shared it more with the thought that it might be interesting than with any 
expectation that anyone would be able to help.  You've already been super 
generous with your time and support!

I'm not sure I follow what you mean by "use the linker from the core snap". 
AFAICS the core snap doesn't contain ld or gcc or any toolchain ... ?

If you mean when building the contents of the snap, I'm just doing a regular 
`snapcraft cleanbuild`, no special magic to select particular gcc or binutils 
versions.
