catch2-3.5.1.drv fails to build with home reconfigure, but succeeds with build

[Richard Sent]

When reconfiguring my home environment, 
y8sll1zarpy78qi6fgrz9xrpx99hhn3b-catch2-3.5.1.drv fails to build. I can 
run $ guix build catch2@3.5.1 just fine, but the derivation has a 
different checksum from when I'm building with home reconfigure 
(2bdvrgwwbrgzxlpckmzsgwrakf8j6yic-catch2-3.5.1.drv).

My build error log (largely) matches Curaiss's failure for the i686 
build (https://ci.guix.gnu.org/build/3220178/log), but I'm on x86_64.

I attached the log and the two derivations to this email. Clearly home 
is adding stuff to the y8sll derviation, but I'm not entirely sure why 
or how.

The only path forward I can see is remove packages from home until it 
builds again, but having greater insight into what's going on would be a 
huge help.

This problem occurs on multiple machines.

Guix version: 3bf2465faa85b8a14b1cedaad43e2c2d0337cf6b

Appreciate any help!
