No. That will break RHEL 6. (I am also an EPEL packager, and I know what
it feels to push such an update to RHEL ...)

AFAICS, libtiff > 4.0 is required for BIGTIFF support, and RHEL 6 has
libtiff 3.9.4. Again, AFAICS, GDAL's configure can pick BIGTIFF support
automagically when it finds the related version of libtiff. I suppose
RHEL 7 has this support.
