/* Define the redirection macros used throughout most of the IFUNC headers.
   The variant is inferred via compiler options.

   F128_REDIR_PFX_R(function, destination_prefix, reentrant_suffix)
     Redirect function, optionally suffixed by reentrant_suffix, to a function
     named destination_prefix ## function ## variant ## reentrant_suffix.

   F128_SFX_APPEND(sym)
     Append the the multiarch variant specific suffix to the sym. sym is not
     expanded.  This is sym ## variant.

   F128_REDIR_R(func, reentrant_suffix)
     Redirect func to a function named function ## variant ## reentrant_suffix

   F128_REDIR(function)
     Convience wrapper for F128_REDIR_R where function does not require
     a suffix argument.
