commit a7bdda05038d3a95daed5aca7d0d4c6ce755e1d9

    Move __sglue initializations to __sfp()
    
    Moved last remaining  __sglue initializations from __sinit() to
    __sfp(). The move better encapsulates access to __sglue and
    facilitates its decoupling from struct _reent in a follow-on patch.
