    arm: Use internal symbol for _dl_argv on _dl_start_user
    
    The lld does not support R_ARM_GOTOFF32 to preemptible symbol (_dl_argv
    has default visibility).  Use the internal alias instead (one option
    would to use HIDDEN_JUMPTARGET, bu the macro is not defined for
    !__ASSEMBLER__ and I made this patch arm-specific to avoid require to
    check extensivelly on other architecture it this might break something).
    
    Checked on arm-linux-gnueabihf.
