This works for Autoconf/Automake, but not for libtool since libtool
must re-parse command line options passed from the Makefile

If the Makefile quoted the CC argument like

 libtool --mode=compile "gcc -B/blah/whatever -m64" "-O" ...

then it could be made to work since the shell will maintain the quoted
arguments as individual units.
