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?

 <ths> For fakeroot the simplest trigger is "fakeroot file /bin/ls".

 <ths> `Kumba: I haven't found a better one yet.

 <ths> Probably marker symbols around the stub section, and then exclude it from the link map.

 <ths> This needs a ld change.
