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:

     3 I tried to use crosstool-ng to generate a toolchain for Linux on big

     4 endian arm with recent versions of gcc, glibc, etc... but had a few

     5 problems.

     7 It appears that the gcc patch (for gcc 4.2.x)

     8 for big-endian arm (240-arm-bigendian.patch) lacks the change attached

     9 to this mail as 240-arm-bigendian2.patch.
