[PATCH 5/9] ldbl-128ibm-compat: Provide ISO C functions not provided by the _Float128 API

[Tulio Magno Quites Machado Filho <tuliom at linux dot ibm dot com>]

These functions do not exist in the float128 api, but they need to be
provided for long double (*l api) because they are part of ISO C.

This patch only adds the exported symbols that are used by user
programs, i.e. __gammaieee128 and __dremieee128.

	* sysdeps/ieee754/ldbl-128ibm-compat/Versions: Add __dremieee128
	and __gammaieee128.
	* sysdeps/ieee754/ldbl-128ibm-compat/w_lgammaf128.c: New file.
	* sysdeps/ieee754/ldbl-128ibm-compat/w_remainderf128.c: New file.
