This didn't do what I thought it would.
It was my intention to allow enabling this through menuconfig / .config.

With the syntax above menuconfig shows:

│ Symbol: MULTIPLEXER [=n]
│ Type  : tristate
│ Defined at drivers/mux/Kconfig:6
│   Prompt: Generic Multiplexer Support
│   Visible if: COMPILE_TEST [=n]

This means it cannot be selected.

Instead I (think I) should use
default m if COMPILE_TEST

Since my patch-set broke x86_64 allmodconfig and failed merge into 
linux-next,
this presents an opportunity to change the above as well with v9.
