    get_local_realms: work around strange duplication of local_realms
    
    The hidden visibility seems to cause the get_local_realms() function to
    return a NULL pointer, although the local_realms global variable is
    actually assigned. Assembler code shows there are two instances of this
    variable around, one set to NULL, the other to the expected value.
    
    This happened on Gentoo Hardened with gcc 4.6.0-r1.
