We are making an assumption that the triple is homogenous (modulo libcall
differences) across all the bitcode files. Ideally this would be the case, but
build systems being build systems there could be some differences, I'm thinking
about normalised triples where `-march` might differ.
Looking at getLibFuncSymbols it seems like most if not all the variation in
libcall availability is in the environment and I wouldn't expect that to vary
across the build system.
I don't think we need to change anything here, but could be worth stating our
assumptions in a comment.
