I'm slightly confused as to what refers to what here.

What do you mean with "I know that patch" and in what relation is the
GitHub issues? (The comment on GitHub helped us figure out which flags
were needed, but didn't say how, when or where to apply them.)

You applied one patch to LuaTeX (which doesn't work when the user
provides something else than "clang" to CC) and Karl applied a
different one to the TeX Live repository (which works fine to build
the binary, but not for the tests).
