I've tried

DFLAGS=-vgc /usr/bin/dub build --build=unittest

but it doesn't seem to have any effect as it doesn't rebuild 
directly after the call

/usr/bin/dub build --build=unittest

I'm using DUB version 1.5.0

Or is adding a new build configuration, say unittest-vgc, the 
only way to accomplish this?

Setting the dflags in the dub.json should work.

This is what I use for dcompute:

{
     ...
     "dflags" : ["-mdcompute-targets=cuda-210" ,"-oq", "-betterC"],
     ...
}

so just change those flags to "-vgc" should do the trick.

You can also just execute:

export DFLAGS=-vgc

before running dub. That should work since as far as I know 
"export" is needed to make env var visible to other processes 
started from the same shell session.
