[U-Boot] [RFC PATCH v1] powerpc: add --bss-plt to LDFLAGS

[Chris Packham]

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.

Technically this is v2 of
http://lists.denx.de/pipermail/u-boot/2014-September/188365.html but the
solution is so different that I'm treating it as a new patch series.
