Description

CMake native builds fail with this error:

cc1: error: unrecognized command line option '-m32'

-m32 is only defined by GCC for x86, PowerPC, and SPARC.

The following files specify -m32 when the JVM data model is 32-bit:

hadoop-common-project/hadoop-common/src/CMakeLists.txt
hadoop-hdfs-project/hadoop-hdfs/src/CMakeLists.txt
hadoop-tools/hadoop-pipes/src/CMakeLists.txt
hadoop-mapreduce-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-nodemanager/src/CMakeLists.txt

This is a partial regression of HDFS-1920.
