We are talking about distinguishing different compiler
versions !!!!!!!!!
Why on earth would you want to run something conditionally, depending on
which compilers it had been compiled with?

You are talking about a package using a toolchain to require _target_
run-time features. Right, these are occasionally required.
But we are talking about compiler/toolchain features. The cross
compilers/toolchains *never* retrieve anything from a target at
run-time.
If the toolchains require knowledge about a target's runtime feature,
the toolchains must know about it in advance, but the
application/package using the toolchain doesn't have to. It can
compile/link check the toolchain.
