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.
