I was about to apply this, but there's an issue with the licensing. So
while I'm at it, I'm also giving other comments.

The title should be just:

	mksh: new package

Those lines are too long. Please wrap the help text to a length of 72
characters per line.

There is no COPYING file in the source code, so this will cause build
failure.

Where is the information about the licensing coming from? What is this
"MirOS" license?

The man page references https://www.mirbsd.org/TaC-mksh.txt as
containing the legalese. Maybe this needs to also be downloaded, and
used as a license file. At least they clarify what this "MirOS" license
is.

TARGET_LDLIBS does not exist. Have you considered using $(TARGET_CONFIGURE_OPTS) here?

	$(TARGET_MAKE_ENV) $(TARGET_CONFIGURE_OPTS) \
		CPPFLAGS="-DMKSH_S_NOVI=0 $(TARGET_CPPFLAGS)" \
		TARGET_OS=Linux \
		sh ./Build.sh -M

The changes in this file could possibly go to a separate patch.

Thanks!
