gtest linking warnings with static builds on cray systems

```
../../lib/libgtest.a(gtest-all.cc.o): In function `testing::internal::StreamingListener::SocketWriter::MakeConnection()':
gtest-all.cc:(.text+0x3af47): warning: Using 'getaddrinfo' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking
```
[ 4%] Built target blt_gtest_smoke

Start by reproducing the static build on a Cray system and tracing the gtest linking configuration that emits the getaddrinfo warning. Done means the static build no longer produces this warning while the blt_gtest_smoke target still succeeds.
