That looks like a kludge to me. You can probably achieve the same effect with
a script filtering out the unsupported flag.
Agreed. That bug that needs to be fixed in the branch.
But that's correct: the final say over --with-gnu-as is in config.gcc. Without
my patch, you have a disagreement between auto-host.h and config.gcc (hence
tm.h ultimately) if the latter overrides -with-gnu-as, which can potentially
lead to inconsistencies like in the linker case.
So, why do we have the --with-gnu-as flag then?
Eric, shouldn't the whole section testing for GNU as move after the
inclusion of config.gcc?
I don't think so, that would change the semantics of --with-gnu-as.
That's my point. After your patch, --with-gnu-as has no meaning. The
user has no way of overriding the value guessed by config.gcc.
