Subject: [PATCH] libjson-rpc-cpp: add support for darwin

The libjson-rpc-cpp is linux-specific because of elf patching required
to build on modern systems. This patch makes those patches conditional
so that the package can be used in darwin as well.

Also, this changes some build flags to make the library emit less noise
for consumers.
