Description Peter Kjellerstedt 2018-11-13 22:41:06 UTC 
If the bitbake server is active and tmp is removed/moved away, then tmp/hosttools is not recreated the next time bitbake is run (as long as the server is still active). This is because tmp/hosttools is only created due to the bb.event.ConfigParsed event, which is not fired when an active bitbake server is reused.

Steps to reproduce:

* Enable the bitbake server, e.g., by adding BB_SERVER_TIMEOUT = "600" to local.conf.
* Run `bitbake m4-native`.
* Move away tmp
* Run `bitbake m4-native` again.

Eventually it will fail with "ERROR: Error running gcc  --version:" because gcc cannot be found in $PATH.

A possible solution would be to trigger the creation of tmp/hosttools also on the bb.event.ParseStarted event.

We can't use both bb.event.ConfigParsed and bb.event.ParseStarted for hosttools creation at the same time, otherwise, it would make it create twice. I will send a patch to change it to bb.event.ParseStarted.

We can't use bb.event.ParseStarted to replace bb.event.ConfigParsed for hosttools since it would break fresh build:

I've sent another patch to mailing list to fix the issue:
