When building, gobject-introspection uses tools/g-ir-scanner to build several .gir and .typelib files. To that goal, it internally builds and runs a few small executables linked to libglib2. However, it does not pass them any LDFLAGS that we could pass the buildsystem. So, it either ends up trying to link with the system's libglib2, which may not be instaleld (build breaks), or is installed to an other version (build may break); in either cases, this is not good... g-ir-scanner can use the argument --lib-dirs-envvar to pass a list of library directories to search for. However, during the build process, this is not possible due to the build process calling g-ir-scanner directly without letting the user (us) pass any option. When discussing with upstream, they explained that the only solution in that case was to set and export LD_LIBRARY_PATH to point to the location where the correct libglib2 was installed. Ergo, that's what we do. This fix has the added benefit of allowing the host gobject-introspection to build the host .gir, .rnc, and .typelib files, which some packages may require.
