One option is to just ignore that warning. It looks to me like an
optional feature. Do you know that you need GDAL support? As a non-user
of the mapping pkg, I would start by ignoring that warning and see if I
do need it later.

If you do need GDAL support, the simplest solution would be to install
some version of the GDAL library in your home directory. I haven't done
this, but I assume it would be something like

    - download and extract GDAL source tarball
    - ./configure --prefix=$HOME/gdal
    - make
    - make install
    - install mapping pkg with CPPFLAGS and LDFLAGS set as needed

Another solution might be to file a feature request asking the mapping
package maintainers to consider bundling the GDAL library with the
package ( I'm
not sure if that's a reasonable task for the pkg maintainer or not, but
it's one possible solution.

Another solution might be to file a feature request asking the flatpak
maintainers to include the GDAL library in the Octave flatpak app
( I'm also not
sure if that's a reasonable task, and I'm one of the flatpak
maintainers, but it may be worth reporting and looking at anyway.
