It's likely to depend upon a lot of factors, e.g. the linking options
for photo.2image, the linking options for GDAL, whether GDAL is a
shared or static library, etc.

Also, the GDAL variable is only used for the ILWIS format, and is
larger than the "int" used by photo.2image. Even if the linker merges
the two variables, there won't be any adverse consquences unless you
actually read ILWIS data from within photo.2image (i.e. if it reads a
map which is a link to ILWIS data created with r.external).
