When using litex-hub::vtr package as VTR dependency, the ci gets the following error while performing linking to the vtr binaries:

  lto1: fatal error: bytecode stream in file ‘/home/runner/work/yosys-f4pga-plugins/yosys-f4pga-plugins/env/conda/envs/yosys-plugins/lib/libarchfpga.a’ generated with LTO version 12979.5 instead of the expected 8.1
  compilation terminated.
  lto-wrapper: fatal error: /usr/bin/g++ returned 1 exit status
  compilation terminated.
  /usr/bin/ld: error: lto-wrapper failed
  collect2: error: ld returned 1 exit status

@kgugala do you have any idea what this would be?
