-msoft-float and assembler...

[Scott Bambrough <scottb at netwinder dot org>]

If I try to compile the code below with `gcc -S -msoft-float sf.S`, it seems the
define __SOFT_FP__  is not passed to the assembler.  Should it be?  I ran into
this when building a multilibbed version of libgcj.  There is some assembler in
libffi for calling foreign functions that uses floating point instructions.  I
was trying to conditionally compile that file.
