poudriere-devel -w tar files are sometimes empty for failure (no contained files): an amd64->armv7 cross build example

[Mark Millard]

FYI: This is based on FreeBSD head -r341836 and ports head -r484783 and was an
amd64->armv7 cross build of the port(s) using amd64-native tools.

For the following failure:

. . .
-- Build files have been written to: /wrkdirs/usr/ports/multimedia/gstreamer1-qt/work-qt5/.build
===========================================================================

!!! build failure encountered !!!

The tar file ends up as (note the small size):

# ls -lTdt /usr/local/poudriere/data/wrkdirs/FBSDFSSDjailArmV7-default/default/gstreamer1-qt5-1.2.0_14.tar
-rw-r--r--  1 root  wheel      1024 Dec 20 07:20:08 2018 /usr/local/poudriere/data/wrkdirs/FBSDFSSDjailArmV7-default/default/gstreamer1-qt5-1.2.0_14.tar

For which:

# tar -tvf /usr/local/poudriere/data/wrkdirs/FBSDFSSDjailArmV7-default/default/gstreamer1-qt5-1.2.0_14.tar | more
#

While the above is from a more general build that got there via dependencies,
this repeats for:

# poudriere bulk -jFBSDFSSDjailArmV7 -w multimedia/gstreamer1-qt at qt5

It leaves me wondering if the @FLAVOR use messes up the production of the tar (wrong path used?).
