You'd have to change several other config symbols to boolean as well.

Example with PHY_MT7621_PCI=m:

ERROR: modpost: "rt_sysc_membase" [drivers/phy/ralink/phy-mt7621-pci.ko] undefined!
make[1]: *** [scripts/Makefile.modpost:150: modules-only.symvers] Error 1

Same with MT7621_WDT=m.

ERROR: modpost: "rt_sysc_membase" [drivers/watchdog/mt7621_wdt.ko] undefined!

At that point I stopped looking.
