With LTO builds we get "-Wmaybe-uninitialized" warnings, which break
the build.
These seem false positives to me, due to aggressive inlining. But also
suppressing them with a pragma does not work. So, make them non-fatal
altogether. That is unfortunate, because this warning would be useful
to catch bugs.
Interestingly, when building --with-more-asserts, then the build passes
without warning. Probably because then the inlining doesn't happen.
