Well, the comment in the Makefile right above these lines is:

  # Need -Uarm for gcc < 3.x

so when using gcc 3.4.0, it's probably not required. :)

Yup, running glibc + all apps with softfloat, VFP format.  However,
since the kernel shouldn't use any floating point anyway, I'm not very
sure why they added -msoft-float to the compilation options.  For
kernel compiles, it would be nice to have a -Werror-on-fp option, or
something like that.
