If your main aim is to test the modules' source code rather than the
include files, you can just make another gnulib in a CONFIG_SUBDIR; it
will include all the modules in the gnulibs of the 3 other
CONFIG_SUBDIRs and it will be used just to run the tests.  The other 3
won't include the tests at all, though, so it won't cover things such as
"how does the close module behave when this other module is included,
*and* when it is not".
