Subject: [PATCH] gobject-introspection: wrapper: add .libs to LD_LIBRARY_PATH
 for emulator

fixes issues like
libdbusmenu-gtk3-aarch64-unknown-linux-gnu> /build/libdbusmenu-16.04.0/libdbusmenu-gtk/tmp-introspect2jhtiwwn/.libs/DbusmenuGtk3-0.4:
error while loading shared libraries: libdbusmenu-glib.so.4: cannot open shared object file: No such file or directory
in non-meson builds

i think the reason we need this in all non-meson builds is because of ./pkgs/development/libraries/gobject-introspection/absolute_shlib_path.patch
