The existing AC_CHECK_LIB test was trying to find a symbol that was not, apparently, exported by the library. Having used the strings command to examine the lib revealed a function we can use successfully for the test.
In addition, the AC_CHECK_HEADERS was only partially finding the Criterion header files; turns out -I including them in bothCFLAGS and CPPFLAGS (even though we don't have any C++ in the project) gets the test to pass properly. Updated README.md to document this.
