RFC: Possible change in DejaGnu/Automake integration

The discovery of bug#47382 
(<URL:https://debbugs.gnu.org/cgi/bugreport.cgi?bug=47382>) has led to 
follow-on effects and efforts to resolve this issue have led to an 
interesting question:  how are existing projects communicating 
build/host/target triplets to their DejaGnu testsuites and would adding 
this information to Automake-generated site.exp files be useful?

I am asking this now because the next DejaGnu 1.6.3 release candidate is 
now expected to use EXTRA_DEJAGNU_SITE_CONFIG to insert this information 
into its own site.exp file and I am considering working the feature into 
an upstream Automake patch to add 
build_triplet/host_triplet/target_triplet to all Automake-generated 
site.exp files at some unknown future date.
