When testing with this configuration on my Debian testing system, the
build fails because guix-daemon fails to build due to "-flto" options.
I am using GCC 5.4.  I don't know anything about link time optimizations
so maybe I am overlooking something.

can you print the output of:

 ./pre-inst-env which guix-daemon

and

 ./pre-inst-env guix-daemon --version

Thanks.
