+Subject: [PATCH] ldso: AVR32 startup hack
+
+AVR32 needs to do both PERFORM_BOOTSTRAP_GOT and a full relocation of
+the GOT. I don't quite remember why, but I think it's because some GOT
+entries just need the load address added to them, while the rest need
+the full relocation code.
+
+This patch should be revisited to figure out whether we're processing
+relocations against undefined symbols and whether that's something we
+should be doing...
