RTEMS 4.7.99.2 Available -- PowerPC/virtex feedback

I think you're absolutely right- inspection by objdump is definitely
indicated.

I ended up using the newlib printf suite as the test- if fp registers
are shown in the instructions, then it meant I had a build problem w/
newlib.  The assembly is dramatically different when the fp registers
are excluded.
