Out-of-tree build can provide better support when integrating FlexiCAS into complex projects like spike-sdk-spec2017.
flexicas.mk.in:
by replacing .. to @top_srcdir@, autoconf is able to find correct path of precompiled static libraries libflexicas.a and cryptopp/libcryptopp.a , otherwise we need to mannually copy these two libs to build directory.
When building under ../flexicas/build, the macro @top_srcdir@ still evals to ... Therefore the change is harmless.
flexicas.ac:
Empty file, but necessary for configure.ac under parent project, e.g. spike-flexicas/configure.ac
