So tinfoil.parse_recipe("multiconfig:arduino-101-sss:gcc") and
tinfoil.parse_recipe("gcc") then return identical data, because both end
up parsing "/data/master/poky/meta/recipes-devtools/gcc/gcc_6.3.bb"
without taking the "arduino-101-sss" config into account?

That wouldn't be correct.

As far as I understand it, the mapping has to be:
multiconfig:arduino-101-sss:gcc ->
multiconfig:arduino-101-sss:/data/master/poky/meta/recipes-devtools/gcc/gcc_6.3.bb
