    hurd: Initializy _dl_pagesize early in static builds
    
    We fetch __vm_page_size as the very first RPC that we do, inside
    __mach_init (). Propagate that to _dl_pagesize ASAP after that,
    before any other initialization.
    
    In dynamic builds, this is already done immediately after
    __mach_init (), inside _dl_sysdep_start ().
