please compile opa-fm with flag '-fPIC'

Fedora and RHEL requires compile C/C++ code with strict options for security enhance. So, executables must be linked with '-pie' flag. That needs the C/C++ files compiled with '-fPIC' flag.

Please consider apply this patch.

Closing along with the other issue. This is 5+ years old and -fPIC is being added.
