Linker error on bootstrap.sh

[niklasnisbeth]

Running the bootstrap script on (Void) Linux, I get the following error:

It turns out the dependency 'conda' ships its own linker which shadows the system linker.

The following command fixes the error for me:

$ mv litex-buildenv/build/conda/compiler_compat/ld litex-buildenv/build/conda/compiler_compat/loving-ld

This makes build use my system linker and the bootstrap script runs to completion. I have not verified the resulting toolchain.
