Ah! I understand now. Thank you.

Yes, but note that _FILE_OFFSET_BITS could be set in config.h, in which
case the grep won't find things, so the set of affected packages could be
larger than you're detecting. Packages that use Autoconf's
AC_SYS_LARGEFILE macro will generally put those settings into config.h
instead of on the command line.
WebAuth is indeed a false positive because WebAuth never attempts to
enable large file support, but there may be other packages that do via
config.h.
