Don't you need to update clang, too?
clang-5.0: error: unsupported option '-fsanitize=leak' for target
'i386-unknown-linux-gnu'

> People keep asking LSan to be available on 32 bit targets (e.g. https://github.com/google/sanitizers/issues/403)

> that may contain random binary data (e.g. browser), but for smaller apps situation is not so terrible and LSan still might be useful.
> This patch adds initial support for x86 Linux (disabled by default), ARM32 is in TODO list.
> We used this patch (well, ported to GCC) on our 32 bit mobile emulators and it worked pretty fine
> thus I'm posting it here to initiate further discussion.
