There's nothing like that in the (older) version I've been using (V3.6.1).
In fact in tif_open.c, there doesn't appear to be any compile time
endian dependent code. HOST_BIGENDIAN seems to be defined in
tiffconf.h, but not used anywhere except tools/ras2tiff.c.

So it looks like compile time endian dependent code has been introduced
at some stage. I would suspect it's quite unnecessary (ie. could have
been coded differently.)
