 This is a nice one. The problem is not netbsd-6 as build host vs. netbsd-5,
 but a 64bit build host vs. a 32bit one.
 
 Gennassym creates the constant in question as:
 
 assym.h:#define A_SUN4V_TLB_TSB_LOCK 1152921504606846976
 
 while the original definition is:
 
 pte.h:#define SUN4V_TLB_TSB_LOCK        0x1000000000000000UL
 
 
 I don't remember right now wether there was some special asm syntax to make
 gas on 32bit hosts understand 64bit constants (this all sounds like a
 gas bug to me).
