Sebastien,

It seems the GDAL library was not included in your link line.  You can likely
just edit MapServer's Makefile and set set the GDAL_LIB something like:

GDAL_LIB=-L/root/applications/mapserver/gdal-1.2.0b -lgdal

More generally, there were some problems with GDAL 1.2.0 with the output
of the gdal-config command that sits "within the build".  One approach to
work around this might be to install GDAL into a tree somewhere (ie. make
install).  It might also be helpful to see what gdal reports if you do:

   gdal-config --libs
