Fix detection of clang "optimization arguments"
In version 3.6.0, clang added -Wignored-optimization-argument. Without
setting this flag to -Werror, "ignored optimization arguments" such as
(for example) -fpeel-loops, are accepted but warned about, leading to
noisy builds if meson thinks the flag is supported.
