commit d4e157aaaead89474366f58fa57e035441a2bd8b

    Remove __libc_creat function name.
    
    glibc has lots of __libc_* function names that no longer serve any
    purpose (are not used for any calls or exported at a public symbol
    version).  This patch removes __libc_creat.  It has the effect of
    creat becoming a strong symbol instead of a weak symbol in various
    cases, but that's fine; in shared libraries it doesn't matter at all,
    while for static linking the only other symbol sometimes defined in
    the same object is creat64, and whenever creat64 is a reserved name so
    is creat.
    
    Other such cases of unnecessary __libc_* symbols are expected to be
    dealt with in separate patches over time.
    
    Tested for x86_64 (testsuite, and that the disassembly of installed
    shared libraries is unchanged by the patch).
    
    	* include/fcntl.h (__libc_creat): Remove declaration.
    	* io/creat.c (__libc_creat): Rename to creat.
    	(creat): Do not define as alias.
    	* sysdeps/unix/sysv/linux/alpha/creat.c (creat64): Define as alias
    	of creat instead of __libc_creat.
    	* sysdeps/unix/sysv/linux/generic/creat.c (__libc_creat): Rename
    	to creat.
    	(creat): Do not define as alias.
    	[__WORDSIZE == 64] (creat64): Define as alias of creat instead of
    	__libc_creat.
    	* sysdeps/unix/sysv/linux/syscalls.list (creat): Do not define
    	__libc_creat name.
    	* sysdeps/unix/sysv/linux/wordsize-64/syscalls.list (creat):
    	Likewise.
