I'm actually going to take one step further. Since icc defines the symbol
__ICC (again thanks to I'm gonna try running the cpp to
detect ICC and then avoid setting some options.

When doing this, I can detect icc pretty accurately. What options would make
sense to set in this case? I mean when building --enable-debug with icc.

I've also moved out this logic into a separate "function" (AC_DEFUN) in
acinclude.m4, so that it will become easier to just copy this function to the
ares source tree.
