Thanks to the combined efforts of reasonable quantities of alcohol and
several people who know significantly more about this sort of thing than
me, it now works. /usr/include/sys/stat.h rewrites fstat() to
__fstat13(). The fstat() in libfakeroot therefore gets rewritten to
__fstat13(). The fstat in libfakeroot calls fstat() in libc, which simply
calls __fstat13(). Sadly, since libfakeroot is LD_PRELOADed, this calls
the libfakeroot version. Which calls fstat() again. Altering libfakeroot
to call __fstat13() rather than fstat() makes things work, but this is
likely to break if the version name changes again in the future. I'm not
sure what a more long-term fix is.

Many thanks to Tony Finch and Peter Benie for working this out, because
I'd never have got there myself.
