With some versions of gcc (that we know of 4.6.3 and 4.8.2 are affected) it is necessary to specify --bss-plt to get the final blrl in the _GOT2_TABLE_. Without this the last symbol does not get it's address relocated. For the P2041RDB board this ended up being NetArpWaitTimerStart which caused the ARP packets to timeout immediately.
