build: disable libstdc++ debug containers globally
Browse files Browse the repository at this point in the history
Different parts of the debug build were using differently sized
std::vectors due to `_GLIBCXX_DEBUG` sometimes being defined and
sometimes not. That ended about as well as you would expect.

Remove the flag.

Fixes: #30056
