I think that the following scenario might work:

We would write a shell wrapper, which would run the compiler, investigate
its output and then exit with the right exit code.

At the beginning of the configure script, some tests would decide whether
the copiler is broken or not.  The wrapper would be used only for the
broken compilers.

The autodetection could be performed by the same script, the wrapper.

Since the wrapper would be an external script, it could be upgraded
independently on the main configure script, similarly as the config.guess
script.

This solution would not affect the normal platforms.

But who would be interested to invest his time into this work?
Perhaps the firms selling the broken compilers could sponsor this work,
if they would think this moght be cheaper than fixing the compiler.

Have a nice day,
