 Log Message:
 named: use liburcu-mb on netbsd.
 
 make libucru use RCU_MB by default.
 fix the liburcu-signal library name (built but unused.)
 
 on netbsd, RCU_MEMBARRIER is identical to RCU_MB, except with some
 extra code run at init time (in a ctor) and then falling back to
 being identical because that code ultimately hard coded to fail.
 
 this reduces the startup code very minimally, and avoids using
 a linux-specific version (that has fallback for old linux that
 works on netbsd.)  it also avoids the problem in PR#59571, though
 the problem seen there is 100% still a problem, and i'll file a
 separate PR about that problem.  (i'm hoping to provide a minimal
 test case, but so far it is not very small.)
