1. Update to m-c tip (currently hg rev 2e4bef09de27)
2. Remove your objdir
3. Run |mach try -b do -p linux64 -u mochitest --tag apz -t none|

Expected:
Try push

Actual:

This works if I take out the |--tag apz| argument.

That make command looks like it's trying to build something.. so not task configuration.  I don't know what it is, though.
