When calling the recursive varient of matchpattern, it doesn't call the function with the matchlength argument. This patch fixes it. Also, set Makefile CC to gcc when GNU/make can't find the default CC path. This fixes compilation on other Unix-like platforms where CC defaults to clang (we previously explicitly set this to GCC).
