You will need to define a BSP that is little endian capable.

The BSP should define:

 DEFAULTTUNE ?= "mips32r2el"

You can verify the setting using bitbake -e and inspecting the value of
DEFAULTTUNE.  The BSP should set that value -before- the necessary line:

require conf/machine/include/tune-mips32r2.inc


(Note, Little endian is not nearly as well tested as big endian for mips.  I
expect you will find some bugs, we'll be happy to take back any fixes for those
issues.)
