Leading tab, not spaces.

Maybe add a bit of help here:
    help
      Install the MySQL server on the target.

Maybe this ifeq-block can be moved in the other one, below?

I noticed that you enable the server with: --with-embedded-server
but you disable it with: --without-server

There is a mismatch between the --with and the --without options. Is
that normal?

No indentation on that first line.

We usually indent with one tab in continuation lines.

These should be indented with a tab, not spaces.

Hmmm... When I suggested we only build the required stuff, I did not
expect this would amount to so many single-line calls.

I wonder if it is worth keeping this. So, is it much faster to only
build the above, compared to building everything? If so, we just keep
the above lines, otherwise, we should just keep the default host build
commands.

> +define HOST_MYSQL_INSTALL_CMDS
> +        $(INSTALL) -m 0755  $(@D)/sql/gen_lex_hash  $(HOST_DIR)/usr/bin/

One tab, not spaces.

It looks like you somehow lost the final line in your refactoring:
    $(eval $(host-autotools-package))

Really, thank you for staying on-board through these iterations!
We're getting pretty close on that last patch! :-)
