gnat regressions on sparc, mips and x86

Hi,

I have re-run GNAT/RTEMS on a number of targets
for 4.3.4, 4.4.1 and the SVN head.  I kept the
binutils, gdb, newlib and RTEMS the same.  The SVN head
has a lot of new failures for SPARC, MIPS, and x86.
The SPARC and MIPS have the same number of failures
(319) so I assume the same underlying cause.

The x86 has gone from about 20 failures which
are mostly deficiencies in qemu FPU accuracy
to about 225 with many indicating hardware exceptions.

And FWIW I was unable to build ARM on the head. :(

I am attaching my summary notes but would appreciate
any feedback.
