   20160418:
           libedit needs manual removal of all autogenerated files since
           some of them are not autogenerated anymore.
   
   20160410:
           amd64 needs full "make cleandir" or deletion of objdir now that
           PIE has been enabled for amd64.  PIE, or position-independent
           executables, means all code, including executables and not just
           shared libraries, is position-independent and hence able to be
           relocated by ASLR, address space layout randomization.
   
           The change was made in Makefile variables for compiler and
           linker flags, for which make(1) does not record dependencies,
           hence it is unable to detect that all .o files need rebuilding.
   
           Partial rebuilds with some modified source files will likely
           fail when linking executables, since the linker refuses to mix
           position-independent code with position-dependent code in
           position-independent executables:
   
                   .../x86_64--netbsd/bin/ld: foo.o: relocation R_X86_64_32 against `...' cannot be used when making a shared object; recompile with -fPIC
   
   20160401:
           Ports switching to GCC 5.3 will need a full "make cleandir".
           Some people have found that cleandir is not sufficient, so if
           in doubt delete the entire object directory tree for gcc.
   
   20160306:
           NetBSD's regexp implementation is now part of libnbcompat.
           Nblex, nbm4, nbpax, nbsed use it and they may crash on
           non-NetBSD hosts if linked with stale object files produced
           while they included a non-NetBSD regex.h.
           In any case, you should "make cleandir" at least these tools
           before updating your toolchain.
   
   20160125:
           Dtrace has been enabled by default on some architectures.
           When doing an update build, make sure to clean the etc/mtree
           object directory before starting the build - otherwise the
           needed directories in destdir will not be created.
           An easy way to do this is:
              cd src/etc/mtree && $TOOLDIR/bin/nbmake-$arch cleandir
   
   20150818:
           New acpica requires "make cleandir" in src/external/bsd/acpica
           again.
   
   20150413:
           New acpica requires "make cleandir" and reinstalling yacc
           in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and
           also "make cleandir" in /usr/src/external/bsd/acpica.
   
   20150404:
           Lint changes require a full rebuild of the tool, so make
           sure to build without -u option to build.sh, or manually
           do a make cleandir in src/tools/lint1 and
           src/usr.bin/xlint.
   
   20150310:
           Improvements to openssl for arm mean that update builds of
           the openssl libraries will fail. A make cleandir in
           external/bsd/openssl/lib is needed
