the dependency libraries are _only_ useful if you link against the static 
version of gdal, i.e. libgdal.a. they are _not_ needed in the normal case 
when you link against gdal as a shared library (at least on linux).

so normal apps should use --libs:
$ gcc my-app.c `gdal-config --libs`

and apps statically linked should use both --libs ad --dep-libs:
$ gcc -static my-app.c `gdal-config --libs` `gdal-config --dep-libs`
or
$ gcc my-app.c /path/to/libgdal.a `gdal-config --dep-libs`

i think the two options should remain separate to keep the normal case of 
dynamic link less confusing. furthermore a user usually knows if he is going 
to link gdal statically and he can act acordingly.

just my two cents, if you are still of the opinion that the options should be 
merged i'll merge them.

cheers,
