I think the issue here is that the default bfd architecture for mips
is 32bit (mips:3000).  When the input is 'binary', the linker
generates objects of this architecture, and this object cannot be
linked to n32 or n64 executables.

The definition is in contrib/binutils/bfd/cpu-mips.c, in definition of
bfd_mips_arch. But to change this, we will need to patch the GNU
contrib code...

Another solution is to use 'objcopy -B mips:isa64' (which can set the
bfd architecture) to convert the binary to elf object instead of using
'ld'.
