Fix for evbarm build release failures

[Petri Laakso <petri.laakso%asd.fi@localhost>]

Hi

CVS checkout was from about Sat Feb  2 19:22:44 UTC 2013 and I had few issues 
with it.
I was running "./build.sh -j4 -m evbarm -u -U release".

After applying following patches I was able to successfully build the release.
