Noticed this when looking at app-office/gnucash which was disabling GUILE_AUTO_COMPILE entirely (see 72dbf2ec4049df11ad63576971883ee239eadb7f).

We don't want Guile making decisions based on the system cache
files. Always recompile so we're deterministic.

See https://www.gnu.org/software/guile/manual/html_node/Environment-Variables.html#index-GUILE_005fAUTO_005fCOMPILE.
