Emulator tasks have some additional parameters not found in other
tasks. Therefore, builds can have an 'additional-parameters' field in
which specific task template replacements can be passed to trygraph.
This field is optional.
Moreover, the syntax for job_flags.yml builds was changed a bit.
Now, instead of:
builds:
<platform>:
types:
opt: <task>
debug: <task>
The syntax is:
builds:
<platform>:
types:
opt:
task: <task>
additional-parameters:
<parameter 1>: <value>
<parameter 2>: <value>
...
debug:
task: <task>
additional-parameters:
<parameter 1>: <value>
<parameter 2>: <value>
...
