The archived source code is missing src/compat/setenv.h

The archived source code, which can be found at https://download.bitcoinabc.org/0.18.5/linux/src/bitcoin-abc-0.18.5.tar.gz (which is the source code stripped of the github specific files/directories), is missing file src/compat/setenv.h

When compiling, this give error:

qt/test/test_main.cpp:9:10: fatal error: compat/setenv.h: No such file or directory
#include "compat/setenv.h"
^~~~~~~~~~~~~~~~~
compilation terminated.
Makefile:8895: recipe for target 'qt/test/qt_test_test_bitcoin_qt-test_main.o' failed

That was with version 0.18.5, but I suspect the issue is present also with older releases

As for the compile environment, I don't think this is really the issue here, but for info, this was compiled under Ubuntu 18.04 (native), gcc/g++ 0.7.3, on AMD Ryzen 2700X, 64GB RAM, 1TB NVMe.

The github release https://github.com/Bitcoin-ABC/bitcoin-abc/archive/v0.18.5.tar.gz does have this file. And copying the missing setenv.sh file to the extracted archived sources does make the compilation process succeed.

Compare the archived 0.18.5 source at the provided download URL with the GitHub release archive, focusing on src/compat/setenv.h. Reproduce the failure by building the qt test target that includes qt/test/test_main.cpp; done when the archived source contains the required header and compilation succeeds.
