Riss does not biuld a .so library for riss+coprocessor as required for IPASIR

[nmanthey]

When using dynamic linking against the IPASIR interface, two libraries would have to be used for Riss, as Coprocessor comes in its own library.

Similarly to the static library, add a rule to build a dynamic library, and build it when IPASIR is build.

Hi @nmanthey, it's me again 😃 Long time no see!

Isn't there the riss-coprocessor-lib-shared target when the FPIC option is enabled (see CMakeLists.txt#L150)? This is a combined shared library of riss and coprocessor.

Yes, true. This file is generated: ./lib/libriss-coprocessor.so. Let's close this.
