I build Gimp 2.8.x and 2.10.x on CentOS 7 (with the almost complete set
of dependencies and dependencies of dependencies and the
cross-dependency hell) too, and didn't face this situation.

Did you build the 2.10.20 sources against the old gegl, then build the
new gegl and rebuild gimp without doing a `make clean`?
