Make runs each command in a makefile in a separate subshell.  For
efficiency, if a command contains no shell metacharacters, it might exec
it directly, and that applies to that "cd" line.  If you want the "cd" to
be useful, do something like "echo here; cd ... && echo there".

Incidentally, the fact that "cd" can't be exec'ed in NetBSD is technically
a breach of POSIX.2.  See PR standards/11197.
