Hi,

I noticed that libatomic implementation for builtin function parameter
smaller than word.
It would shift the parameter value to word and then store word.
However, the shift amount for big endian would be wrong.
This patch fix libatomic builtin function behavior for big endian toolchain.

Is it ok for trunk ?

Shiva
