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.

The gcc-3.x toolchains would contain all the targets by default.  With gcc-4,
thomas@1461
     6
you have to actually list out the multilibs you want or you will end up with
thomas@1461
     7
just one when using targets like 'sh4-linux-gnu'.

The resulting toolchain can't even build a kernel as the kernel needs to build
thomas@1461
    10
with the nofpu flag to be sure that no fpu ops are generated.

Here we restore the gcc-3.x behavior; the additional overhead of building all
thomas@1461
    13
of these multilibs by default is negligible.
