[5/6] ldbl-128ibm-compat: Provide ieee128 symbols to narrow functions
Commit Message
From: Tulio Magno Quites Machado Filho <tuliom@linux.ibm.com>
Move the narrow math aliasing macros into a new sysdep header file
math-narrow-alias-float128.h. Then, provide an override header
to supply the necessary changes to supply the *ieee128 aliases of
these symbols.
This adds ieee128 aliases for faddl, fdivl, fmull, fsubl, daddl, ddivl,
dmull, dsubl.
