Fix building ltrace on PowerPC.

ltrace wouldn't build on PowerPC because in the
sysdeps/linux-gnu directory in the ltrace source tree
the powerpc directory is called ppc. I added some code
in 400-ltrace.sh to create a symlink for it so it will
build now.

Patch slightly modified by me before applying.

 # Bare metal config options

 config KERNEL_bare_metal

     select BARE_METAL

     help

       'Bare metal' refers to those programs that run without any kernel.

       You probably want to say 'y' here if you plan to use your compiler

       to build bootloaders. It is not yet suitable to build Linux kernels,

       though, because the APCI stuff relies on the target C library headers

       being available?!?!...
