ppc: cleanup unsupported ppc64 code
Remove ppc64 bits and bytes, as we don't support ppc64 and it makes the code more readable without the dead code.

-include/bits is mostly the same as glibc-2.2.4. The glibc-2.2.4
-versions can be accessed with the tag glibc224.
-
-Major differences:
-
- - termios.h is from the Linux kernel, not glibc, because glibc has
- a very strange legacy conversion layer, which we ignore.
-
- - syscall.h is deleted; instead, sysnum.h is autogenerated in uClibc
-
- - syscalls.h is added.
