Support building with older glib versions It is desirable to be able to build against older versions of glib. fd7a245 changed the configure check to require glib > 2.38 for G_TEST_DIST. Before that, version 2.16 was required, but in fact, since aafe395, G_PASTE is being used, which was introduced in 2.19.1. And since 0ef179e2, hb-glib uses GBytes, which were introduced in 2.31.10. 2.19.1 is rather old, but 2.38 is rather new. For Firefox, building against 2.22 is still supported, although we could probably get away with bumping that to 2.28. Either way, GBytes is not available. Arguably, if you build against a glib that doesn't support GBytes, you're not going to use the hb_glib_blob_create function, so we hide the function when building against such a glib. As for G_TEST_DIST, when building against versions of glib that don't support it, we can fallback to the previous behavior, which, AIUI, was just making the test not work when building in a separate directory.
