Many thanks for this fix.

Merged into "master-next".

While the file fetcher doesn't have that option, it was the fact that
it didn't have it that kept things working.

If you use subdir, then in fact, a recipe space BSP doesn't work at
all as the tools can't find the BSP definition.

The kernel-yocto bbclass is what is using this to set up search paths
for kernel features when it sees the type=kmeta.

The option could have had a less confusing name (since it is
effectively passthrough like "type=kmeta", but that's not something
that I'm willing to change right now (I'll do it post release)

But the documents are correct, you do need destsuffix or the
recipe-space BSP will  not work.

Oh, interesting. Perhaps the recipe-space BSP works this way, but the 
recipe-space additions for other parts of 'kmeta' didn't work for me. 
Whenever I wanted to extend kernel features that yocto-kernel-cache 
didn't have, I had to use subdir.
