Are you suggesting that hosts should define HOST_*_FORMAT?  Or should
we attempt to eliminate the HOST_*_FORMAT macros entirely?

(The only HOST_*_FORMAT macro currently defined is HOST_LONG_DOUBLE_FORMAT
and it is only defined by some i386 hosts.)

BTW, you'll need to address the use of HOST_FLOAT_FORMAT in
arm_linux_push_arguments() in arm-linux-tdep.c or else that file
won't compile any longer after eliminating the defines from defs.h.
