bug#54037: Guix commands throws after running `sudo -i guix pull` on foreign distro. Wrong guile version used for regular user.

[Simen Endsjø]

Not sure if this is a bug, or if it's somehow my fault.

I'm using Guix on a foreign distro, and I think I broke my system after
running `$ sudo -i guix pull`.  When running `$ guix pull` I get
lots of warnings like the following

    ;;; WARNING: loading compiled file (.. snip ..) failed:
    ;;; In procedure load-thunk-from-memory: incompatible bytecode version

And commands like `pull` and `update` throws exceptions. I've tried
rebooting my system to no effect.

Both roots and my `realpath $(which guix)` returns
`/gnu/store/rkm49zf7gk3xj94bnscjsr3c1vaam977-guix-command`.
This is a shebang script, calling
`/gnu/store/549xzhnm3q810py1v0jbv0px0prd3a21-guile-wrapper/bin/guile`.

The strange thing is that the wrapper script invokes a different version
of guile for root and my user. Root doesn't have guile installed, while
my user have guile installed. That script uses 3.0.8 for root and 3.0.7
for my user. Discussed this on IRC yesterday, and another user had a
similar setup, but the script retured 3.0.8 for both users.

bug#54037: LD_LIBRARY_PATH=$LIBRARY_PATH caused wrong libraries to be loaded

[Simen Endsjø]

My guess is I wanted to force the foreign distro to load a guix
installed library (when compiling something on the foreign distro..?
can't remember). Running `$ LD_LIBRARY_PATH= guix pull` works as normal.
So this is, as it most often is, an user error. Sorry for the noise.
