See: https://stackoverflow.com/questions/33206409/unused-dt-entry-type-0x1d-arg 

This is somewhat consistent with the fact that the termux support for your particular android platform is not particularly robust.  This, the glob issue, and the compiler issue mentioned below are all signs of this lack of robustness.

The test failure you're seeing says that the compiler you're using doesn't generate code to correctly implement the needs of ANY of the VAX simulators.  The same problem absolutely exists on the vax simulator, but the available diagnostic merely doesn't happen to demonstrate that failure since it doesn't do the same things as the VAX780 diags.  Trying to run real programs on any VAX simulator on your platform will certainly not be perfect.

As previously mentioned, we've seen issues with some of the older Android versions, and E8 is probably doesn't have a very beefy CPU compared to the S8.

You got it right, but it won't change the build and test time since that really is limited by the CPU power of the system you're running on and it has nothing to do with whether or not glob functionality is available.
