Khem Raj d7b8ad5c29 eglibc: Upgrade recipes 2.16 -> 2.17
Drop patches that are applied upstream

Fix the license checksums for changes in LICENSES file
the new changes add more copyright notices that were missing earlier

Moving ports is no longer needed since ports is now part of libc proper

Refresh tzselect-sh.patch to accomodate upstream changes

C++ headers discovery relative to target sysroot is fixed differently
upstream hence we drop use-sysroot-cxx-headers.patch

aarch64 support is already available in 2.17 hence drop the local
patches

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.
