[Yaffs] link error (unresolved reference __aeabi_uldivmod) i…

I am attempting to configure yaffs2 into the kernel, and the linker errors
out thusly:

  LD      .tmp_vmlinux1
fs/built-in.o: In function `yaffs_internal_read_super':
yaffs_mtdif2.c:(.text+0x59a34): undefined reference to `__aeabi_uldivmod'

Searching ml:yaffs didn't yield any related threads. Please, guidance or
gentle correction would be most appreciated!
