Is this the prescribed way to do things nowadays? It leads to more
options showing up in 'make menuconfig'. Why do I need to see
CLKSRC_PXA if I'm not even compiling for ARCH_PXA (and not interesting
in COMPILE_TEST)?

This bit makes sense.

That won't happen.

As the 'bool' has no string after, it won't show up in the menuconfig.

Actually, with the next patch, only COMPILE_TEST will show it up in the

Device Drivers->Clocksource drivers.
