location for compiled guile files

[Song Koh]

When you start gnucash for the first time, it compiles some guile files 
and saves them at $HOME/.cache/guile/ccache/...

Since I clean my cache oftenl before backups, they are recompiled each 
time.

Is there a more central location for these files?  Like 
/usr/lib/gnucash, or /usr/share/... ?

I am using Linux Mint which is a Debian based system.
