Excellent.  Applied, thanks!

That size for busybox uclibc seems awfully big, even for being
staticly compiled...   Do you have debugging enabled?  Or did you
enable a bunch of busybos applets?  Clearly, getting shared
libraries working will help a great deal.

BTW, I removed the arch special cases here.  This creates a
pipe.o file, but that is then replaced by the arch specific one.
