eglibc: Add recipes for 2.16 release

Drop the patches that were either applied
or fixed differenly in 2.16

Add patches to fix ppc spe patches to match
eglibc 2.16

Fix CPPFLAGS to contain correct includepaths
so autoconf cache is generated correctly

+The default lib search path order is:
+
+  1) LD_LIBRARY_PATH
+  2) RPATH from the binary
+  3) ld.so.cache
+  4) default search paths embedded in the linker
+
+For nativesdk binaries which are being used alongside binaries on a host system, we 
+need the search paths to firstly search the shipped nativesdk libs but then also
+cover the host system. For example we want the host system's libGL and this may be
+in a non-standard location like /usr/lib/mesa. The only place the location is know 
+about is in the ld.so.cache of the host system.
+
+Since nativesdk has a simple structure and doesn't need to use a cache itself, we 
+repurpose the cache for use as a last resort in finding host system binaries. This 
+means we need to switch the order of 3 and 4 above to make this work effectively.

+If you build & install glibc w/rpc disabled, you no longer have headers in
+/usr/include/rpc/ (this is expected).  But if you try to build glibc w/rpc
+enabled, this gets into a bad state due to the new rpc helpers that get
+cross-compiled:
