    cad/netgen: fix build
    
    ld: error: libsrc/interface/libinterface.so: undefined reference to
            pthread_create [--no-allow-shlib-undefined]
    
    This has been happening for over a month since an LLVM update
    made it more sensitive to symbol-issues. I can't spot any
    direct pthreads usage in the source, though, so the patch
    is just a bodge.
