   1 Subject: [PATCH] ldso: AVR32 startup hack
   2
   3 AVR32 needs to do both PERFORM_BOOTSTRAP_GOT and a full relocation of
   4 the GOT. I don't quite remember why, but I think it's because some GOT
   5 entries just need the load address added to them, while the rest need
   6 the full relocation code.
   7
   8 This patch should be revisited to figure out whether we're processing
   9 relocations against undefined symbols and whether that's something we
  10 should be doing...
