It's certainly possible; ffconf.h's definition of _FS_READONLY is
already driven by CONFIG_FAT_WRITE in this series.
I'm not sure if it's worth it though; on the RPi, turning off volume
label support only saves ~0.5K of .text, 0 .data, and 8 bytes .bss. If
so, I can certainly throw in another patch to allow it to be configured.
