How to change the tmp directory location in ember apps

Is there a way to change the location of the tmp directory ember-cli is using to process trees? (without using symlinks)

I am trying to develop an ember app using a linux VM on a windows host. Shared folders of any type (be it virtualbox shared folders, nfs or smb) are slow, don't allow symlinks and ember-cli produces a lot of files in the tmp directory. Being able to move this tmp to the native filesystem of the VM would help a lot.

This should be easily configurable, but i couldn't find any configuration option that would allow it.
