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

[Jason Wessel]

Please understand I have no idea how gdk-pixbuf-native is supposed to compile.  Perhaps you can elaborate further as to why g-ir-scanner cannot be called in this case.  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. 

Looking at the log files from the compilation phase it appears to use meson as the build tool.  The compile log file indicates that it is using the pkg-config tool to find g-ir-scanner and subsequently use it.
