I think we absolutely want to share the .tbl files for generating all
five outputs
(32-bit unistd.h, 64-bit unistd.h, 32-bit native syscall-table.S, 64-bit native
syscall-table.S, and 32-bit compat syscall-table.S) so we only
have to modify one file when adding another syscall, and to ensure that
 32/64 are in sync.
