Ahh, right. So the ESX generator explicitly sets the files readonly when
it creates them. So when they are in the dist, and the stmp file is not,
you hit the EPERM issue.

I copied the make rules from the python generator, which also does not
include the stamp file in dist. The difference is though that the python
generator doesn't make its files readonly
