malloc_get_state and malloc_set_state have been obsoleted, meaning that 
they are not included in any new ports, are not included in static libc 
for any port and in shared libc in existing ports they are compat symbols 
that new binaries can't be linked against.  (Yes, the testsuite work to 
support ports postdating that obsoletion is still needed.)

You can probably build the testsuite with "make check" without setting 
test-wrapper, presuming you've fixed all issues with compilation of the 
testsuite, then rerun "make check" with test-wrapper specified to run the 
execution tests.  I don't know whether transferring the build directory to 
a different system for a native "make check" would work, but at least lots 
of tools would be required on the target to do so.
