gegl: Disable pango on native build to fix gimp build segfaults
gegl: Disable pango on native build to fix gimp build segfaults

Achieve by adding a PACKAGECONFIG for pango and keep that out of native.

* pango support is not required for gimp build
* pango support caused random segmentation faults building gimp. To work around
  vector support was disabled for many arches.
  Am not sure but segfaults might be caused by missing font configuration on
  native:
  | Fontconfig error: Cannot load default config file
  Now with upcoming pango 1.48.7 build of gimp build is broken completely: All
  calls of gegl caused segfaults.
