The -Wunused-local-typedefs warnings seem to have been recently introduced in
g:9a0b518a82db68c5cbd9ea8ccc47c2ff45182519 commit.
Same c++2020 warnings are reproducible on GLIBC targets when running:
$ make check-target-libstdc++-v3 -k RUNTESTFLAGS="conformance.exp=stdc\+\+*.cc
--target_board=unix/-Wall/-Wsystem-headers/"
