Edit the dump so that the databases are created with Linux-compatible
locale names.  You should find lines like

CREATE DATABASE foo WITH TEMPLATE =3D template0 ENCODING =3D 'UTF-8' LOCAL=
E_PROVIDER =3D libc LOCALE =3D 'tr-TR';

(details will vary depending on PG version) and changing the locale
strings ought to do the trick.

If the dump file is too big for your editor, consider splitting it
into schema-only and data-only dumps.
