It is fully generic. I added it in

testsuite: Introduce be/le selectors
It is very useful, just like ilp32 / lp64 :-)

Yes. powerpc64le-linux is the only problematic thing (you can make
powerpc64-linux be LE as well, and in principle you can make
powerpc64le-linux be BE, that just doesn't work right now -- this all
*does* work for powerpc-linux and powerpcle-linux).
Implicit assumptions make everything harder.
