toolchain/binutils: fix broken build of binutils 2.34 on mips64

Commit 53470bdf32 ("toolchain/binutils: Add binutils 2.34") logs refreshed
patches, but also adds a typo causing failed builds on mipsel64 platforms,
including the malta subtarget. Update the patch to fix this.

This fixes the following build error:
make[7]: *** No rule to make target 'elf64ltsmip.o', needed by 'ld-new'.  Stop.
