configure: Fixed linker options when checking for amqp_tcp_socket_new.

This fixes the check when using GCC's --as-needed which fails when options are
not specified in the right order. Libraries (-l options) have to be specified
after any source files. autoconf does the right thing when using $LIBS for
that case rather than $LDFLAGS.
