Subject: [PATCH] glib-2.0: relocate the GIO module directory for native builds

Instead of hard-coding GIO_MODULE_PATH when glib is built, use dladdr() to
determine where libglib.so is and use that path to calculate GIO_MODULES_DIR.

This solves relocation problems with GIOModule for native builds of glib.
