Building 4.5.0 beta1c

[Joel Sherrill]

The ts_386ex has no hardware FPU.  Therefor, it depends on gcc to
provide
soft-float libraries.  The person who submitted this BSP had an i386
soft-float patch for egcs that was not merged.  There is another
unmerged
i386 soft float patch floating on the gcc lists.  That is the
functionality
you are missing.

I encourage everyone who has used an i386ex and RTEMS with soft-float
to work with the gcc maintainers to get this patch tested and merged.
If someone gets it merged, then I can add it to the gcc RTEMS patch
and RPMs until it shows up in the main distributions.
