Unload modules failure on Sparc Solaris

Unload modules failure on Sparc Solaris

[Vin Shelton]

On the Solaris 5.8 Sparc box here at work, I'm getting a coredump in
the V01 modload test:

Running test: Delete the module alias again
Test successful.
Running test: Unload the modules loaded by this test suite
Segmentation Fault - core dumped
make: [check] Error 139 (ignored)

Here is the backtrace:
