Recent changes to the MIPS binutils sources have made it necessary for
GCC to pass the -msoft-float to the assembler if it wants an object
file marked as soft-float. This patch makes GCC pass any -mhard-float,
or -msoft-float flags that were used on the compile line on to the
assembler so the executable is marked appropriately. I did not do
anything with -mno-float because the GNU assembler doesn't have a
-mno-float flag.
Without this patch (and a second one I will submit shortly) I cannot
build soft-float multilibs with the latest GCC and top-of-tree binutils.
Tested with the mips-mti-linux-gnu toolchain.
OK to checkin?
