    disable always failing tst-signal7
    
    The required test for the internal NPTL used signals isn't
    implemented.

    Remove alias.
    
    open_cancel and open2_cancel have diffrent argument on open.
    So can't alias this functions.

    openat argument fix.
    
    If argument passing to register case (ex. -mregparam=3).
    This case set all parameters set to register from caller.
    But callee refer to stack. So can't get parameter.

commit de272b8d01d6367d2c607b6cef3a68cbb547666b

    pthread_atfork handlers not removed during dlclose
    
    Invoke pthread_atfork handler cleanup when removing the associated DSO...
    
    If a program loads a DSO (dlopen) that sets up a pthread_atfork handler(s), and
    then subsequently closes the DSO, the handler(s) are left in place.  If fork()
    is subsequently called, the handlers are invoked even though the DSO has been
    removed causing crashes or unpredictable code execution.  This is because the
    code in __cxa_finalize(atexit.c)to invoke the unregister_atfork() routine is
    ifdef'd out with the comment that it hasn't been "looked into this yet...".

    extra/Configs/Config.in: add syncfs() to Linux-specific functions
    
    syncfs() was recently added (commit dfa593d4d).  But man sync(2) specifies
    that syncfs() is Linux-specific.  This was overlooked in the original
    commit so we add it to the set of Linux-specific functions supported by
    uClibc.

commit 95581e1079a50bd9e56129e9c319a748555783a2

    libc/inet: Unbreak gethostent()
    
    Although gethostent() is obsoleted, there is no reason to keep it broken.
    Fix two problems:
    
    * commit f65e66078b "resolver: switch to config parser" leave an extra break
      statement in case of GETHOSTENT in __read_etc_hosts_r. In result,
      output buffer wasn't initialized at all.
    
    * gethostent static buffer has insufficient size to store aliases,
      so __read_etc_hosts_r always returns ERANGE. Restore ALIAS_DIM define.
    
    Add test-case.
