[PATCH] Fix IPC for PPC (maybe needed for mips and sparc64 too?)

[Franz Sirl]

Hi,

I finally found the reason why some X apps (namely gdm and the gtk+ tree 
example) had problems on Linux/PPC, glibc was treating PPC as a 16bit 
uid_t/gid_t/etc. platform, but this was never the case on PPC, we had 32bit 
from the beginning. The attached patch fixes it. Mips and sparc64 may need 
similar fixes.

	* sysdeps/unix/sysv/linux/kernel-features.h: Always define
	__ASSUME_32BITUIDS for __powerpc__.
	* sysdeps/unix/sysv/linux/powerpc/ipc_priv.h: New file.
	* sysdeps/unix/sysv/linux/powerpc/Dist: Add ipc_priv.h.
