That flag is used for a good reason: using the internal bigtiff-enabled library
instead of the system one, which has also few fixes in respect with libtiff4. 
Those issues will be definitively fixed *when* libtiff5 will be moved in
main (after its definitive release I assume). In the meantime third
parties modules should link in the right order the two libs (gdal and
tiff) to avoid problems.

Another possibility would be adopting GNU ld versioned symbols in the internal
library, which could be used as a dirty trick to work around the
problem: I will do some tests about that.
