Subject: [PATCH] ldbl-128ibm-compat: Introduce ieee128 symbols
This patch adds __*ieee128 symbols for strfrom, strtold, strtold_l, wcstold
and wcstold_l functions.  Redirection from *l to *ieee128 will be handled
in separate patch once we start building these new files.

2018-06-26  Rajalakshmi Srinivasaraghavan  <raji@linux.vnet.ibm.com>

	* sysdeps/ieee754/ldbl-128ibm-compat/Versions: Add __strfromieee128,
	 __strtoieee128, __strtoieee128_l,__wcstoieee128 and __wcstoieee128_l.
	* sysdeps/ieee754/ldbl-128ibm-compat/strfromf128.c: New file.
	* sysdeps/ieee754/ldbl-128ibm-compat/strtof128.c: New file.
	* sysdeps/ieee754/ldbl-128ibm-compat/strtof128_l.c: New file.
	* sysdeps/ieee754/ldbl-128ibm-compat/wcstof128.c: New file.
	* sysdeps/ieee754/ldbl-128ibm-compat/wcstof128_l.c: New file.
