No one disputes that. But you can correct your code to support a $CC value
with arguments:
set x $CC
if (type $1) >/dev/null 2>/dev/null; ....

Exactly that's the reason why we documented it this way in Autoconf:
The triplet detection does not work right if a user puts '-m32' or '-m64'
in $CFLAGS or $CPPFLAGS.

You can have a different opinion about how the Autotools should behave.
But once we have documented how they behave and what a user needs to
do in order to get good results, it's not a "bug" any more.
