Not completely sure but I was thinking that when
before a netbsd emulation loads itself into execsw it
could go through the list of sysent structure, see how
many don't have PTRs and then allocate a new sysent
structure, copy its into it, and replace the calls of
its sysent that don't use pointers with the ones from
emul_netbsd's sysent array.

Now having a string_t or netbsd32_string_t instead
of using const char * would help things like open and
other pathname using syscalls and remove ARG_PTR from
them since the PTR they use isn't really important.
