179c7ef523 [Darwin] Some TLC for older Darwin versions. 
The library handling and some of the options for creating the crts for
the older PPC Darwin versions had bit-rotted somewhat.  This adjusts the
build criteria for the crts to avoid newer ld64 versions warnings about
mismatches in build and object versions.

Added to some of the comments that it's documented why the specs are as
they are.

34a4a9c2b5 Darwin, PowerPC, libgcc - Ensure unwinder is built with altivec enabled. 
When libgcc is built on Darwin, it is usually built for the earliest potential
target (Darwin8, 10.4).  Build for that revision default to assuming that the
processor might be G3 (without vector ops) and there is an outlined function
used for save/restore that checks whether the processor is G3 or G4+ at run-
time.  However, the unwinder itself needs to be built with the assumption of
vector usage so that the relevant outlined functions are called.

ef5eb79dfd darwin, powerpc - set .machine in an asm file. 
The asm file fails to build if we use a modern assembler
which checks that the machine is consistent with the 
filetype.  Fixed by adjusting in a similar manner to 
other assembler.

6395ba73f8 libgcc2.c: Correct DI/TI -> SF/DF conversions 
FSTYPE FUNC (DWtype u) in libgcc2.c, which converts DI/TI to SF/DF, has

  /* No leading bits means u == minimum.  */
  if (count == 0)
    return -(Wtype_MAXp1_F * (Wtype_MAXp1_F / 2));

in the third case (where actually count == 0 only means the high part is
minimum).  It should be:

  /* No leading bits means u == minimum.  */
  if (count == 0)
    return Wtype_MAXp1_F * (FSTYPE) (hi | ((UWtype) u != 0));

instead.
