that says this is a NT executable (PEI) and the magic number that
determines the architecture. The former is DOSMAGIC, stored in
the e_magic field. The latter is stored in the f_magic field.
If the NT magic number isn't valid, the architecture magic number
could be mimicked by some other field (specifically, the number
of relocs in section 3). Since this routine can only be called
correctly for a PEI file, check the e_magic number here, and, if
it doesn't match, clobber the f_magic number so that we don't get
a false match. */
