Merge branch 'bugfix-107-odroid-build' into 'bugfix-48-L1L2signaling'

added fixes to build on odroid/xu4 platform

changes on bugfix-48-L1L2Signaling to build for odroid platform

the branch has been tested to build on x86 platform
- builds for eNB
- can do attach
- can ping external servers

On odroid,
- builds correctly
- eNB fails to come up due to late samples (same as parent branch)
