That should work, assuming the compiler didn't by chance scatter the
bytes B I G E elsewhere in the file.  An alternative might be to send
the file through od and grep the hex output.  This would of course
rely on the data being 4-byte aligned within the file.  I don't know
if any object file format allows non-aligned data.

That makes solaris 10 broken.  The -q flag is standard.
