This provides an extra macro expansion before invoking
the hidden_def macro.  This removes the need for ugly
workarounds when building these files as float128.

	* sysdeps/generic/math_private.h:
	(mathx_hidden_def): New macro.
	* sysdeps/ieee754/ldbl-128/s_finitel.c: Replace
	hidden_def usage with mathx_hidden_def.
	* sysdeps/ieee754/ldbl-128/s_isinfl.c: Likewise.
	* sysdeps/ieee754/ldbl-128/s_isnanl.c: Likewise.
