It can't happen in coreutils.  The current working directory of the
shell CANNOT be influenced by the actions of a child process, which
coreutils would necessarily be.

It can, however, be done in the shell, if your shell author is
interested in writing a builtin version of mkdir (to match the fact that
chdir is already a shell builtin, for what should be obvious reasons).
However, you don't even have to modify the shell source code, but
instead just write a function to do the two steps in one function call.
