Updating superbuild GDAL configuration

Summary

On a environment containing libfreexl gdal automatically link with it. Whereas there is no need and package are delivered without it.

Rationale

There is no need for this. The configure command of GDAL has been updated to avoid this link. I'd like to take this opportunity to make sure that our GDAL is as light as possible. Here is the list of option that we can use in GDAL (there might be more...) :

GDAL configure option	OTB Superbuild value
geos	with
geotiff	with
hide-internal-symbols	none (default without)
libtiff	with
libz	with
threads	with
bsb	none
cfitsio	without
cryptopp	none (default with)
curl	with
ecw	without
expat	with
fme	without
freexl	without (once this is merged)
gif	without
gnm	none (default with)
grass	without
grib	none (default without)
hdf4	with
hdf5	with
idb	without
ingres	without
jasper	without
jp2mrsid	without
jpeg	with
kakadu	without
libgrass	without
libkml	without
mrf	none (default with)
mrsid	without
mysql	without
netcdf	with
odbc	without
ogdi	without
openjpeg	with
pcidsk	with
pcraster	without
pcre	without
perl	without
pg	without
php	without
png	without
python	without
qhull	internal
sde	without
sqlite3	none (default with)
webp	without
xerces	without
xml2	without
spatialite	without

Those without value are a real problem because behavior depends on the plateform they are built on. GDAL configure script is testing whereas the system have the option or not and then use it (most of the time). That is why packaging on hulk are broken, GDAL is using freexl.
Anyway, as I was investigating I thought someone might have something to say about that, so here are the facts!

Here is a for the long facts!
