Thank you for the answer Jeremy.

Nope, this is exactly what I tried before thinking about patching the main wscript.

/build/pkg/samba-4.16.4+dfsg$ make test TESTS=ldb*
PYTHONHASHSEED=1 WAF_MAKE=1  ./buildtools/bin/waf test
'test' finished successfully (0.039s)
Waf: Entering directory `/build/pkg/samba-4.16.4+dfsg/bin/default'
	Selected embedded Heimdal build
Waf: Leaving directory `/build/pkg/samba-4.16.4+dfsg/bin/default'
'build' finished successfully (5.712s)
ERROR: You must use --enable-selftest to enable selftest
make: *** [Makefile:16: test] Error 1

Any value for TEST= causes the main selftest/wscript to be run
which, in turn, verifies that --enable-selftest has been enabled
at configure time.  And this is exactly the place I want to patch
out in order to enable *any* test to be run at all.

Thanks,
