gdb reverse execution: how to actually run tests for it?

I am trying to finally implement the reverse ability for MI commands, but
creating and testing the tests is looking challenging. The fundamental issue is
that it seems that I cannot get the regular reverse tests to run, to know how to
properly code the reverse tests for reverse MI. 

When I run

$ make check RUNTESTFLAGS="gdb.reverse/*.exp"

There is a flurry of activity ending in this:

                === gdb tests ===

Schedule of variations:

Running target unix
Using /usr/share/dejagnu/baseboards/unix.exp as board description file for
Using /usr/share/dejagnu/config/unix.exp as generic interface file for target.
Using ../../../src/gdb/testsuite/config/unix.exp as tool-and-target-specific
interface file.

                === gdb Summary ===

/home/jakob/gdb7/gdb-host-revpatched/gdb/testsuite/../../gdb/gdb version -nw -nx

make[3]: Leaving directory `/home/jakob/gdb7/gdb-host-revpatched/gdb/testsuite'
make[2]: Leaving directory `/home/jakob/gdb7/gdb-host-revpatched/gdb'
make[1]: Nothing to be done for `check-target'.
make[1]: Leaving directory `/home/jakob/gdb7/gdb-host-revpatched'

Which seems to indicate that no tests were actually run. This is a 6.8.50 branch
that I checked out of cvs late last week. 

What is required to actually run the reverse tests? Do I need to build my gdb in
any special way?

I suspect that this line the test scripts is the cause of the premature exit
from the tests:

if ![target_info exists gdb,can_reverse] {

So how do I make gdb realize that it can indeed reverse itself?
