Hack from Debian to hopefully get sandbox working on mips |

<`Kumba> ths: given the SHN_UNDEF thing is a hack, what's the preferred solution? |
| yann@1625 | 4 |
<ths> For fakeroot the simplest trigger is "fakeroot file /bin/ls". |
| yann@1625 | 5 |
<ths> `Kumba: I haven't found a better one yet. |
| yann@1625 | 6 |
<ths> Probably marker symbols around the stub section, and then exclude it from the link map. |
| yann@1625 | 7 |
<ths> This needs a ld change. |
