I think you are mixing up "LICENSE" and "LICENSE_FLAGS". The two don't
really work together. It's partly explained in:

  https://www.yoctoproject.org/docs/2.4/mega-manual/mega-manual.html#var-LICENSE_FLAGS

See the LICENSE_FLAGS comment which says "This value is independent of
LICENSE and is typically used to mark recipes that might require
additional licenses in order to be used in a commercial product. For
more information, see the "Enabling Commercially Licensed Recipes"
section."

To whitelist a recipe which is being excluded due to
INCOMPATIBLE_LICENSE, use WHITELIST_GPL-3.0. For example for
gdbserver, try the following:

  WHITELIST_GPL-3.0 += "gdbserver"
