Stefan Liebler 51213e2b8d S390: Use new s390_libc_ifunc_expr macro in s390 8bit-generic.c. ...

This patch adds s390_libc_ifunc_expr macro which uses the __ifunc base macro
in include/libc-symbols.h and lets the user define a generic expression to
choose the correct ifunc variant.  Furthermore as the base macro is used,
the ifunc resolver functions are now also using inhibit_stack_protector.
S390 needs its own version due to the hwcap argument of the ifunc resolver.

This new macro is now used in iconv code in 8bit-generic.c instead of using
gcc attribute ifunc directly.

ChangeLog:

	* sysdeps/s390/multiarch/ifunc-resolve.h
	(s390_libc_ifunc_expr_init, s390_libc_ifunc_expr): New Define.
	* sysdeps/s390/multiarch/8bit-generic.c
	(__to_generic, __from_generic): Use s390_libc_ifunc_expr to
	define ifunc resolvers.
