Is it possible to set -fdebug-prefix-map via an environment variable or
a similar mechanism rather than through the command line ?

The issue is that adding -fdebug-prefix-map=PREFIX to CFLAGS
leads to PREFIX leaking in buildlogs and in generated Makefiles and 
similar files that can end up inside packages, making previously
reproducible packages unreproducible.
