I would like to have information about this :-)

We do want to retain symbols (and potentially even debugging
information) in the foo.exec files.  But the final images are pure
binary blobs and there is no real use for any of the symbol
information.

In fact, the the way i386 uses this, it outputs "binary" format
images.  I can't even think of where it would place any symbol
tables :-)

On sparc64 this will actually matter, because we need to use
a.out format images for the boot blocks.  If I leave the symbols
in there, this brings the boot block over it's required 512-byte
size.

That's fine with me, I'll update the patch once the strip issue
is resolved.
