To get the test to compile I had to link in tas.o as the attached patch 
shows.  Unfortunately this doesn't work for platforms that don't have a 
tas.o, bailing out with file not found.  Perhaps it's not important to fix 
this test, but I thought I'd mention it.

Anyway the test exits with

Stuck spinlock (80618e9) detected at ./s_lock.c:355.

on a linux gcc build this exits with

Stuck spinlock (0x5013ad) detected at ./s_lock.c:402.
