nativesdk-glibc: Split glibc and libcrypt to use libxcrypt instead

Fedora28[1] has decided to go ahead and use libxcrypt to replace libcrypt from glibc
despite the change not having merged into glibc upstream yet. This breaks the use of
uninative in OE on fedora28 since binaries there are now using new symbols only found
in libxcrypt. libxcrypt is meant to be backwards compatible with libcrypt but not the
reverse.

Since this will impact OE in the next release cycle, this changes nativesdk only
to use this new model and adds libxcrypt to work in that case. This allows us to
build a uninative which is compatible with fedora28 and previous other OSes.

In order to work, recipes will now need to depend on virtual/crypt where they use
libcrypt since its now a separate library and we can't depend on it from glibc to
preseve backwards compatibility since glibc needs to build first. For now, only the
problematic nativesdk recipes have been fixed up. For target use, the default
provider remains glibc for now. Assuming this change is merged into upstream glibc,
we will need to roll this change out for the target but we will do this in the next
release cycle when we can better deal with the resulting bugs.

tweaks.

+From: Zack Weinberg <zackw@panix.com>
+Subject: [PATCH] Deprecate libcrypt and don't build it by default
+
+Back in June, Björn Esser proposed to add OpenBSD-compatible bcrypt
+support to our implementation of crypt(3), and Zack Weinberg replied
+that it might actually make more sense to _remove_ libcrypt from
+glibc, freeing up libcrypt.so.1 and crypt.h to be provided by a
+separate project that could move faster.  (For instance, libxcrypt:
+https://github.com/besser82/libxcrypt)
+
+This patch disables build and installation of libcrypt by default.  It
+can be re-enabled with --enable-obsolete-crypt to configure.  Unlike
+libnsl, we do *not* install a runtime shared library; that's left to
+the replacement.  (Unlike the SunRPC situation, I think we can
+probably drop this code altogether in a release or two.)
+
+The function prototypes for crypt and encrypt are removed from
+unistd.h, and the function prototype for setkey is removed from
+stdlib.h; they do *not* come back with --enable-obsolete-crypt.  This
+means glibc no longer provides the POSIX CRYPT option, and the macro
+_XOPEN_CRYPT is also removed from unistd.h to indicate that.
+(_SC_XOPEN_CRYPT is still defined, but sysconf(_SC_XOPEN_CRYPT) will
+return -1 at runtime.)  These functions are also unconditionally
+removed from conform/data/{stdlib,unistd}.h-data.
+
+        * posix/unistd.h (_XOPEN_CRYPT, crypt, encrypt): Don't declare.
+        * stdlib/stdlib.h (setkey): Don't declare.
+
+        * configure.ac (--enable-obsolete-crypt): New configure option.
+        * configure: Regenerate.
+        * config.make.in (build-obsolete-crypt): New makefile variable.
+        * crypt/Banner: Delete file.
+        * crypt/Makefile: Don't build anything unless
+        $(build-obsolete-crypt) is 'yes'.
+        * sysdeps/sparc/sparc32/sparcv9/multiarch/Makefile: Only add things
+        to libcrypt-sysdep_routines when $(build-obsolete-crypt) is 'yes'.
+        * sysdeps/sparc/sparc64/multiarch/Makefile: Likewise.
+        * sysdeps/unix/sysv/linux/arm/Makefile: Likewise.
+
+        * conform/Makefile: Only include libcrypt.a in linknamespace tests
+        when $(build-obsolete-crypt) is 'yes'.
+        * conform/data/stdlib.h-data (setkey): Don't expect.
+        * conform/data/unistd.h-data (crypt, encrypt): Don't expect.
+        * elf/Makefile: Only perform various tests of libcrypt.so/libcrypt.a
+        when $(build-obsolete-crypt) is 'yes'.
+        * elf/tst-linkall-static.c: Don't include crypt.h when USE_CRYPT
+        is false.
