Fix two issues with AC_LINK_IFELSE for metaSMT:
1. It expects only 2 arguments, so if linking succeeds, nothing will happen (thanks to []),
otherwise the message "checking for new_bitvector() in -lmetaSMT" will appear.
The latter is that what we currently observe, which means linking actually failed.
2. The reason for linking failure is the use of "-lmetaSMT" in LDFLAGS.
AC_LINK_IFELSE does approximately the following: ${CXX} ... -lmetaSMT ${EXECUTABLE_NAME} ${LIBS},
which causes "libmetaSMT cannot be found" (at least on Ubuntu Xenial, where ${LIBS} = -lz).
After consulting https://www.gnu.org/software/autoconf/manual/autoconf-2.66/html_node/Running-the-Linker.html,
adding "-lmetaSMT" to ${LIBS} seems to be the correct solution.
