Build: change back link-time-optimization default to off
I've found that if building PROJ with lto, but GDAL without lto, exceptions
thrown in PROJ are not properly captured by try {} blocks in PROJ C API,
and unexpectedly go back up to GDAL.
Might be a defect of the particular compiler I use (gcc 5.4 Ubuntu 16.04)
