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:

     2  The generated libtool for building libstdc++ adds the -nostdlib option to the

     3  g++ command for linking but doesn't add -lgcc.  This causes a "hidden symbol"

     4  error when linking against the libstdc++ shared object.  This patch adds gcc

     5  to the list of libraries linked against when linking libstdc++.
