Although nobody tried to enunciate a formal policy in the other thread,
I think where we ended up is that we'd consider suppressing warnings
seen with -Og, but only with reasonably-modern compiler versions.
For LTS compilers we are only going to care about warnings seen with
production flags (i.e., -O2 or better).
