Description

On switching from CMake 2.8.6 to 3.3.2 a couple of minor issues popped up:

• There's a syntax error in hadoop-common-project/hadoop-common/src/CMakeLists.txt that generates a warning in 3.X

• CMAKE_SHARED_LINKER_FLAGS is being incorrectly set in hadoop-common-project/hadoop-common/HadoopCommon.cmake - despite the name it contains the flags passed to ar not to the linker. 2.8.6 ignores the incorrect flags, 3.3.2 doesn't and building static libraries fails as a result.

Patch to follow.
