+Subject: [PATCH 01/27] nativesdk-glibc: Look for host system ld.so.cache as
+ well
+
+Upstream-Status: Inappropriate [embedded specific]
+
+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.
