History
H.J. Lu ee417882e0 Don't use hidden visibility in libc.a with PIE on i386 
On i386, when multi-arch is enabled, all external functions must be
called via PIC PLT in PIE, which requires setting up EBX register,
since they may be IFUNC functions.

	* config.h.in (NO_HIDDEN_EXTERN_FUNC_IN_PIE): New.
	* include/libc-symbols.h (__hidden_proto_hiddenattr): Add check
	for PIC and NO_HIDDEN_EXTERN_FUNC_IN_PIE.
	* sysdeps/i386/configure.ac (NO_HIDDEN_EXTERN_FUNC_IN_PIE): New
	AC_DEFINE if multi-arch is enabled.
	* sysdeps/i386/configure: Regenerated.
