How does an eventual missing mkfs.jffs2 inhibit the generation of an

See above. Perhaps you ment to select e2fsprogs for the ext2 filesystem
iff the host doesn't have an mkfs2? But then we seem to use genext2fs so
there is no need for an mkfs.ext2 installed on the host that i can see.
genext2fs should live in the TOOL_BUILD_DIR and not in the BUILD_DIR,
The BR2_TARGET_ROOTFS_JFFS2 already builds an host-mtd automatically, so
again this works (i did try this sometimes ago, it does work indeed).
$ grep _MTD target/jffs2/Config.in -B2
bool "jffs2 root filesystem"
$ grep -e mtd-host$ target/jffs2/jffs2root.mk
$(JFFS2_TARGET): host-fakeroot makedevs mtd-host
Again, paste the error you were seeing, please.
