description:
bootstrap: Enable support for building mksh.

Over time, and as they are tested, platforms will be migrated over to
shells/mksh ($need_mksh) instead of shells/pdksh ($need_ksh) when a
bootstrap shell is required.  Once mksh is selected, it takes precedence
over pdksh.

Our shells/pdksh has been unmaintained for many years and has known
issues, shells/mksh is expected to provide a portable, fast, and well
maintained alternative.
