The code does:

       os_page = os_page_detect();
        if (os_page > PAGE) {
                malloc_write("<jemalloc>: Unsupported system page size\n");
                if (opt_abort) {
                        abort();
                }
                return true; 
        }
        

os_page = 8192 and I presume PAGE = 4096...

From:

#ifndef PGSHIFT
#if defined(_ARM_ARCH_6)
#define PGSHIFT         13              /* LOG2(NBPG) */ 
#else 
#define PGSHIFT         12              /* LOG2(NBPG) */
#endif  
#endif

because the code was not compiled on _ARM_ARCH_6. I will take care of it.
