Feature request: make Guile compiler always write absolute paths in .go files for Geiser compatiblity

[Vili Aapro]

Dear all,

for Geiser (specifically, `geiser-edit-symbol-at-point') compatibility, we 
would like the Guile procedure `program-source' always to return absolute 
paths; for this, we would need compiler co-operation. Specifically, it would be 
desirable to make Guile compiler always write absolute paths in .go files.

At the moment, this is not the case, and `edit-symbol-at-point' fails for 
`iota' because `program-source' returns a relative path "ice-9/boot-9.scm".

We discussed this on `geiser-guile'; see 
https://gitlab.com/emacs-geiser/guile/-/issues/33 .

Thank you,
Vili Aapro
