modload broken on evbarm?

# Resending. Sorry if duplicated.

Hi,

I'm trying an evaluation board that equips TI AM3352
and have got an error on modload.

  # modload nand
  kobj_checksyms, 880: [nand]: linker error: symbol `__ffssi2' not found
  WARNING: module error: unable to affix module `nand', error 8
  modload: Exec format error

I could fix the issue by fixing
common/lib/libc/arch/arm/string/ffs.S like this:

  -WEAK_ALIAS(__ffssi2,ffs)
  +STRONG_ALIAS(__ffssi2,ffs)

But I don't know if the fix is correct.

Are there someone succeeding to load modules
referring __ffssi2 on evbarm?

Note that my build instructions are something like this:
./build.sh -U -j 5 -m evbarm tools
./build.sh -U -j 5 -m evbarm kernel=BEAGLEBONE
./build.sh -U -j 5 -m evbarm kernel=BEAGLEBONE distribution
./build.sh -U -j 5 -m evbarm kernel=BEAGLEBONE sets

Thanks,
