omagic/nmagic/zmagic binaries from guest account on
Lord Isildur's tahoe system (thanks). enabled if both
COMPAT_43 and COMPAT_VAX1K are defined.
basically rewrote exec_vax1k_prep_anymagic() to handle more
file formats. we remove vax1k_subr.c because we now use the
standard vmcmd_readvn function.
XXX: suspect the code for MID_VAX1K NMAGIC binaries is wrong,
need a binary to confirm this... the old code did not pad the
end of the text segment to a page boundary, and that seems wrong.
you definitely need to pad it on a 4.3BSD NMAGIC binary and i
don't see why MID_VAX1K should be different?
