Note that such configure tests could only readily be in the library 
configure scripts, not in the compiler configure scripts - you can't do 
target compile or link tests in host-side configure.  (To a limited extent 
it's possible to grep target headers in host-side configure, though not to 
actually preprocess them since the compiler required for such 
preprocessing doesn't exist at that point.)
