newlib is only used as a bootstrap mechanism before you build a "real" C library.

busybox will work with uclibc or glibc.  I recommend glibc, but due to size
limitations you may want to use uclibc.  (Be aware that uclib isn't as well
supported on PPC.  At least wasn't last time I looked..)

glibc is much larger then uclibc, but is a "full featured" c library (w/ shared
library support).  There many ways to shrink down the size of glibc to something
more manageable for an embedded project, but it will probably still not be as
small as uclibc.
