1. linux/bootstrap-tools: move libstdc++ out of default library search path …

   This change allows building new gcc during bootstrap without fear of
   pulling in outdated libstdc++.so after g++ switched from bootstrapTools
   to freshly built g++.
   
   Noticed when tried to add early bootstrap stage to rebuild `gcc` before
   `glibc` is fully untangled from `bootstrapTools` as a failure to built
   `binutils`:
   
       ld: dwp.o: in function `__gnu_cxx::new_allocator<gold::Dwp_output_file::Contribution>::allocate(unsigned long, void const*)':
       /nix/store/...-gcc-11.3.0/include/c++/11.3.0/ext/new_allocator.h:116: undefined reference to `std::__throw_bad_array_new_length()'
   
   The change survives existing bootstrap and unblockes early `gcc` bootstrap.
