include/apr_general.h use
#if defined(CRAY) || (defined(__arm) && !defined(LINUX))
#ifdef __STDC__
#define APR_OFFSET(p_type,field) _Offsetof(p_type,field)
#else
#ifdef CRAY2
#define APR_OFFSET(p_type,field) \
        (sizeof(int)*((unsigned int)&(((p_type)NULL)->field)))

#else /* !CRAY2 */

#define APR_OFFSET(p_type,field) ((unsigned int)&(((p_type)NULL)->field))

#endif /* !CRAY2 */
#endif /* __STDC__ */
#else /* ! (CRAY || __arm) */

apr_hints.m4 has
    *-linux*)
        case `uname -r` in
	    2.* )  APR_ADDTO(CPPFLAGS, [-DLINUX=2])
	           ;;
	    1.* )  APR_ADDTO(CPPFLAGS, [-DLINUX=1])
	           ;;
	    * )
	           ;;
        esac

So when `uname -r` start with 3 on arm, LINUX is not defined

I would suggest this change as the value assigned to LINUX value is never used
