    Do not enable DT_INIT_ARRAY/DT_FINI_ARRAY on uclinuxfdpiceabi
    
    Commit r12-1328 enabled DT_INIT_ARRAY/DT_FINI_ARRAY for all Linux
    targets, but this does not work for arm-none-uclinuxfdpiceabi: it
    makes all the execution tests fail.
    
    This patch restores the original behavior for uclinuxfdpiceabi.
