From: William Roberts <william.c.robe...@intel.com>

When the Kernel UAPI header is present, this error occurs:

external/selinux/libselinux/src/policy.h:7:9: warning: 'XATTR_NAME_SELINUX' 
macro redefined [-Wmacro-redefined]
\#define XATTR_NAME_SELINUX "security.selinux"
        ^
bionic/libc/kernel/uapi/linux/xattr.h:52:9: note: previous definition is here
\#define XATTR_NAME_SELINUX XATTR_SECURITY_PREFIX XATTR_SELINUX_SUFFIX

Just use the kernel UAPI version on that case.
