9fa03ecd01 Add parentheses where required. Without them, `sizeof LDBL_MAX'
is a syntax error and shouldn't be, while `1 FLT_ROUNDS' isn't a
syntax error and should be.  Thanks to bde for the examples.

86d131a04a Implement FLT_ROUNDS for arm. Some (all?) arm FPUs lack support for
dynamic rounding modes, but FPUless chips that use softfloat can support it
because everything is emulated anyway.  (We presently have incomplete
support for hardware FPUs.)

6fc729af63 Import FreeBSD/arm kernel bits.
It only supports sa1110 (on simics) right now, but xscale support should come
soon.
Some of the initial work has been provided by :
Stephane Potvin <sepotvin at videotron.ca>
Most of this comes from NetBSD.
