x86: Add back _end symbol that is missing from Symbol.map

With 2.6.31 'crash' on x86_64 falls flat on its face as the
'_end' symbol is missing from the System.map file.

The culprit is commit 091e52c3551d3031343df24b573b770b4c6c72b6,
which moved the '_end' symbol into it's own section. Apparently
this causes kallsyms to not reference it properly.

So do not include _end in it's own section.
