true. the full story is that we need HAVE_STAT64 for a multi-arch
strace so it can decode stat syscalls correctly. so really it was me
turning on HAVE_STAT64 (in our Android makefile) after applying this
aarch64-only fix that broke x86_64. strictly speaking, this was the
change that broke the build:

it's an Android git/gerrit thing. i wanted to use "git format-patch"
to send you the patch rather than just "git diff" which means i have
to commit, and committing automatically assigns a Change-Id. since
i'll just abandon my change and then cherrypick and submit whatever
you submit upstream, this is meaningless. the cherrypick will get a
new Change-Id.
