Thanks for the patch series! This has the potential to shave off a day 
of my build times.

I applied the first 5 patches of this series locally on top of 
cc4b392a8303788762ed9adb9c5635cf227e58a2, but it fails to build. The 
sixth patch fails to apply, also.

I have a few other patches (openssl, libpng, etc) but I don't think 
they're related to the failure.


I'm getting the following:

   builder for
   `/gnu/store/h08fh16kcvs90f3vmw9l6vh83czdhd4i-rust-1.77.1.drv' failed
   with exit code 1
   build of /gnu/store/h08fh16kcvs90f3vmw9l6vh83czdhd4i-rust-1.77.1.drv
   failed
   View build log at
   '/var/log/guix/drvs/h0/8fh16kcvs90f3vmw9l6vh83czdhd4i-rust-1.77.1.drv.gz'.

And the contents of the log file above are the following:
