Yes, that works, IIRC the same was done for the historical binary

If stdout/stderr is accessible after build, then the relevant 
logs can just be cat'd.  For the testsuite, these be 
./gcc/testsuite/gdc/gdc.log and 
./x86_64-pc-linux-gnu/libphobos/testsuite/libphobos.sum 
(substitute the target where necessary).

In the event of failed builds, or builds where the success/fail 
status changed, perhaps.  Having emails for every build would 
just be noise.
