[PATCH] Hide reference to mktemp in libpthread

[Andreas Schwab <schwab at suse dot de>]

mktemp is no longer in POSIX, and this also avoids the link warning when
linking -lpthread statically.

Andreas.

	[BZ #14327]
	* include/stdlib.h (__mktemp): Add declaration.
	* misc/mktemp.c (__mktemp): Renamed from mktemp, add weak alias.
	* misc/Versions (GLIBC_PRIVATE): Add __mktemp.

	* sem_open.c (sem_open): Use __mktemp instead of mktemp.
