We cannot fix package headers downstream, so we can just as well tell the compiler to not warn about them.

# Hack: On LLVM, use `-isystem` instead of -I to ignore warnings about the
|
|
# package's headers. On g++ (at least the AVR variant), `-system` is C
|
|
# only. But luckily, g++ does not emit the warnings we need to ignore
|
|
# anyway.
