binutils/binutils: remove faulty patch

The added code should be conditinal to the target system
being !MIPS, but is based on the host system being !MIPS.

This is plain wrong, and had not been noticed until now
as I never used those binutils versions on MIPS.

See:

     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.
