     1 	Hack from Debian to hopefully get sandbox working on mips
     2 
     3 <`Kumba> ths: given the SHN_UNDEF thing is a hack, what's the preferred solution?
     4 <ths> For fakeroot the simplest trigger is "fakeroot file /bin/ls".
     5 <ths> `Kumba: I haven't found a better one yet.
     6 <ths> Probably marker symbols around the stub section, and then exclude it from the link map.
     7 <ths> This needs a ld change.
