    toolchain: fix dangling symlink to self in FixupLibdir
    
    This avoids a dangling symlink to self when reinstalling the toolchain:
    
    ./staging_dir/toolchain-mips_24kc_gcc-9.3.0_musl/lib/lib -> lib
    
    This is caused by the fact that in the toolchain dir we have
    
    'lib64 -> lib'
    
    and on executing
    
    'ln lib ./staging_dir/toolchain-mips_24kc_gcc-9.3.0_musl/lib64'
    
    ln dereference the symbolic link 'lib64' to 'lib' so the REAL command is
    
    'ln lib ./staging_dir/toolchain-mips_24kc_gcc-9.3.0_musl/lib'
    
    this results in the dangling symlink to self.
