Apparently the "future hard error" is treated as an error.
It looks like clang does not understand the gcc argument
'-mno-fused-madd'. Only the developers of Inferno would know if
multiply-add for float caveat is really a requisite for Inferno.
So look if there is the equivalent in clang, and convert the
argument; or suppress it where it is defined in the mkfiles (perhaps
it is necessary for gcc, doing "things", and not necessary with
another compiler, so the compiled program will not exhibit any
problem).
