Wouldn't it be easier to just test within configure whether $AR supports 
response files like this? And then emit a flag to config.mak which allows 
picking which codepath to take here.

Alternatively we could look for specifically targeting the fix to Windows 
- however, it's not enough to look for the target OS - it needs to look at 
the host OS. Crosscompiling for Windows on unix won't need it, and the 
converse, crosscompiling on Windows targeting Linux would also need the 
same fix.

So just checking whether the feature is supported by $AR might be the 
simplest.
