There are typically two approaches in Buildroot packages :

 * Either the .mk file does not use the "make install" target the
   package makefile to install the package to the target/ directory and
   manually installs only what's needed for runtime usage of the package
   software ;

 * Or the .mk file does use the "make install" target of the package
   makefile to install the package to the target/ directory and then
   cleans up the files that are not really needed for runtime usage of
   the package.

In the case of the libglib2 package, manually doing the package
installation to the target is maybe too complicated, so the second
solution is probably the easiest one. It would be something like:

define LIBGLIB2_REMOVE_DOCUMENTATION
 rm -rf $(TARGET_DIR)/usr/share/gtk-doc
endef

LIBGLIB2_POST_INSTALL_TARGET_HOOKS += LIBGLIB2_REMOVE_DOCUMENTATION

Cheers,

Thomas
