[bug-inetutils] Configure For Hard Float

[Nathan Royce]

I've been encountering this in everything I've built so far (lzlib, plzip, git, flex, bison, iproute2...)

Essentially it fails looking for "stubs-soft.h" when hard float is being used and even set in CFLAGS (mfloat-abi=hard).

The tip I was given from the lzlib developer before it was fixed in the dev pre-release is to set CC="$CC $CFLAGS".
