commit 6253bacdc00de132dec452ff7c6ce3ba7fa23d81
Author: H.J. Lu <hjl.tools@gmail.com>
Date:   Sat Mar 10 09:27:04 2018 -0800

    Remove hidden __libc_longjmp
    
    Since __libc_longjmp is a private interface for cancellation implementation
    in libpthread, there is no need to provide hidden __libc_longjmp in libc.
    
    Tested with build-many-glibcs.py.
    
    	* include/setjmp.h (__libc_longjmp): Remove libc_hidden_proto.
    	* setjmp/longjmp.c (__libc_longjmp): Remove libc_hidden_def.
    	* sysdeps/s390/longjmp.c (__libc_longjmp): Likewise.
    	* sysdeps/unix/sysv/linux/sparc/sparc64/longjmp.S (__libc_longjmp):
    	Likewise.
