Comment (by saagarjha):

 The TL;DR is that the configure check (AC_CHECK_FUNC) doesn't actually
 look at the headers to see if stat64 is available, it forward declares it
 with a bogus signature and then tries to link it. On Apple silicon this
 succeeds because the symbols still exists even though the headers don't
 define it. I'm not an autoconf expert, but maybe we should be using a
 check that only looks at the headers?
