[OE-core] [PATCH] gobject-introspection.bbclass: Disable writing to $HOME/.cache/g-ir-scanner

[Alexander Kanavin]

Generally because generating introspection data is disabled for native
packages, as a matter of policy (do not build something which is
unused and untested).

If you could add
EXTRA_OEMESON_append_class-native = " ${GI_DISABLE_FLAG}"

to the gdk-pixbuf recipe, and re-test (without your fix, to be extra
sure) that g-ir-scanner is not invoked and nothing shows up in its
cache, I would appreciate.

I did not observe any obvious way that the g-ir-scanner was explicitly disabled for the build of the -native package with in the do_configure stage.
