NetBSD always saves a_midmag as big-endian, but libbfd use the same

Browse Source 
endianess as the arch in its internal structures, so we may have to change
the byte order when we write the exec header. The problem is that we need
the little endian version for libbfd to DTRT with the rest of the file.

Solve this by writing the exec header after the rest of the file has been
written.
