The value provided here is passed to the -s/--sub-page-size
option of ubinize.

bool "Use custom config file"
help
Select this option to use a custom ubinize configuration file,
rather than the default configuration used by Buildroot (which
defines a single dynamic volume marked as auto-resize). Passing
a custom ubinize configuration file allows you to create several
volumes, specify volume types, etc.
As a convenience, buildroot replaces the string
"BR2_ROOTFS_UBIFS_PATH" with the path to the built ubifs file.
So the volume defined for the root filesystem can specify the
image path as: image=BR2_ROOTFS_UBIFS_PATH
