There is an undocumented macro AC_NO_EXECUTABLES which turns off the 
behavior you're talking about when placed before AC_PROG_CC. 
Unfortunately it can and probably will disappear someday.

The other approach is to add CFLAGS="-c" before and CFLAGS="" after 
AC_PROG_CC, to make autoconf think that it links an executable, when in 
fact it doesn't. But that's just an ugly hack.
