831486a2d3 Turn the assembly optimized memcpy (simple rep movsd) back on for x86. Had to hack around the make system a bit, and the result is pretty nasty, specifically due to the amount of places in the system where various targets poke their fingers into the libroot directory.
The solution is less than optimal, but should work for now.

a83c8bbffa Moved libroot/posix/kerrno.c to kernel/lib/ where it belongs, and renamed it to kernel_errno.c.

dedf1bccfe Since we're using floating point values at several places in the kernel, I added
a very simplistic floating point output routine to snprintf() and friends, for
your convenience.

e55e1a0e66 Implemented the PPC specific RTC support. We search for an "rtc"
device in the Open Firmware implementation of boot loader and
pass its path to the kernel, where it's opened and used for
getting/setting the real time. The expensive atomic_*64() on PPC
32-bit make things a bit more complicated. Moreover, missing
64 bit multiplication and division instructions won't really
allow system_time() to be anywhere near as fast as on x86. :-/

957a1b17eb * Introduced new build system variables
{HAIKU,HOST,TARGET}_KERNEL_PIC_{CC,LINK}FLAGS which define the
  compiler/linker flags specifying the kind of position independence
  the kernel shall have. For x86 we had and still have -fno-pic, but the
  PPC kernel has -fPIE (position independent executable) now, as we
  need to relocate it.
* The boot loader relocates the kernel now. Mostly copied the relocation
  code from the kernel ELF loader. Almost completely rewrote the PPC
  specific relocation code, though. It's more correct and more complete now
  (some things are still missing though).
* Added boot platform awareness to the kernel. Moved the generic
  Open Firmware code (openfirmware.c/h) from the boot loader to the kernel.
* The kernel PPC serial debug output is sent to the console for the time
  being.
* The PPC boot loader counts the CPUs now and allocates the kernel stacks
  (made OF device iteration a bit more flexible on the way -- the search
  can be restricted to subtree). Furthermore we really enter the kernel...
  (Yay! :-) ... and crash in the first dprintf() (in the atomic_set()
  called by acquire_spinlock()). kprintf() works, though.

353d20c0c5 * libroot and the runtime loader are no longer built with kernel rules.
* New rule Ld, analogously to KernelLd.
* Added StaticLibrary parameter for supplying additional objects.

38f6264454 Reorganized building of kernel, boot loader, and libroot.
Each component is built in the respective subdirectory now
and no longer in src/system/Jamfile.
