Probably, it doesn't exist. There is no System V ABI even for alpha.
ELF ABI for vax is effectively defined by

(1) GCC; see src/external/gcc/dist/gcc/config/vax and
(2) kernel; see src/sys/arch/vax

A potential problem is that (1) and (2) are sometimes inconsistent;
this once caused a problem for alpha; see thread
