[bug#78102] [PATCH] gnu: Add redumper.

[Gabriel Wicki]

LGTM

but unfortunately the 'adjust-CPLUS_INCLUDE_PATH phase does not work in
cross-compilation context.  do you think it is possible to get this to
work?  that would be really awesome.

the error i'm getting says:
> error: in phase 'adjust-CPLUS_INCLUDE_PATH': uncaught exception:
> wrong-type-arg "string-append" "Wrong type (expecting ~A): ~S" ("string" #f) 
> (#f) 

thanks for your time and effort!
