Post #1234619

@raboof @sj Not sure how it's going with or what happened to the Nix bootstrap efforts. I do know that integrating the next version of the full source bootstrap in Guix, with support for RISC-V, dropping ancient GCC's and Glibc's is still taking time. Also, meanwhile the bootstrap is being streamlined even further, which should allow dropping many of the bootstrappable tcc patches and probably/hopefully even a native x86_64 bootstrap. So it may be a feature to "wait" for all/some of these to land in Guix. Cc: @ekaitz_zarraga @efraim @emilyposting
