+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.

+
+This patch scratches an itch.  Each individual gcc command in the
+glibc build is over 1K, which means it takes up a good chunk of my
+terminal.  Most of that is include paths.  Any version of GCC new
+enough to build glibc supports response files, which were added in
+2005.  So use a response file for the static list of include paths.
+Now the build commands are a lot shorter, and easier to use when
+developing glibc.
+
+Tested on x86_64-linux-gnu.  Please apply if acceptable.
