Unfortunately I noticed we had a performance regression in buildtimes in
recent changes. The closest I have this narrowed down to so far:

https://autobuilder.yocto.io/pub/non-release/20210314-14/testresults/buildperf-ubuntu1604/perf-ubuntu1604_master_20210314181831_d42487bf52.html

suggests it may be this change. I have more tests queued to confirm
that definitively, if so we'll have to figure out why as this shouldn't
really happen, its an 8% regression :(.

Cheers,

Richard
