nspr-native: fix ubuntu 18.04 builds using system gcc.

gcc   abstract.o -Xlinker -L../../dist/lib -lplc4 -L../../dist/lib
-lnspr4 -lpthread -lrt -o abstract
../../dist/lib/libnspr4.so: undefined reference to `dlopen'
../../dist/lib/libnspr4.so: undefined reference to `dlclose'
../../dist/lib/libnspr4.so: undefined reference to `dlerror'
../../dist/lib/libnspr4.so: undefined reference to `dlsym'
../../dist/lib/libnspr4.so: undefined reference to `dladdr'
collect2: error: ld returned 1 exit status

Pulling in -lrt, does not automatically pull in libdl.
