[PATCH] (resend with patch attached) PPC32 vfork support and misc small fixes

[Franz Sirl <Franz dot Sirl-kernel at lauterbach dot com>]

Hi,

this patch adds PPC32 vfork support to glibc, modeled along the other arches.

Besides that the patch optimizes the INTERNAL_SYSCALL macro by using the new 
ERR parameter, saving a few instructions on every use. The change to 
syscall.S takes the possible extra register need for 64-bit argument 
alignment into account.

BTW, since I'm the interim PPC32 maintainer, how do I subscribe to 
libc-hacker?

Franz.
