Removed definition of PPC_ABI and PPC_ASM as there are now defaults
that reflect the GNU toolset.

23#  NDEBUG (C library)
24#     if defined asserts do not generate code.  This is commonly used
25#     as a command line option.

27#  RTEMS_TEST_NO_PAUSE (RTEMS tests)
28#     do not pause between screens of output in the rtems tests
29#
30#  RTEMS_DEBUG (RTEMS)
31#     If defined, debug checks in RTEMS and support library code are enabled.
32#
33#       
34#  PPC_VECTOR_FILE_BASE (PowerPC)
35#     This defines the base address of the exception table.
36#     NOTE: Vectors are actually at 0xFFF00000 but file starts at offset 0x0100
37#       
38#  PPC_USE_SPRG (RTEMS PowerPC port)
39#     If defined, then the PowerPC specific code in RTEMS will use some
40#     of the special purpose registers to slightly optimize interrupt
41#     response time.  The use of these registers can conflict with
42#     other tools like debuggers.
