linux-yocto-dev: Handle performance regression

Browse Source 
After commit 0437a59e3c, the linux-yocto-dev
recipe is being parsed every time we run "bitbake -p". This was spotted
on some performance benchmarks and showed up as a performance regression.

We can tweak the recipe to ensure this doesn't happen and that its only
used if selected.
