btw, it seems impossible to have

...
ssl_protocols TLSv1.2;
...

and a testresult of

SSLv2 NOT offered (ok)
SSLv3 offered
TLSv1 not offered
TLSv1.1 not offered
TLSv1.2 not offered

are you sure you have tested the right machine?

i'd suggest you run the testssl.sh - script against https://localhost:443
on the machine where you build nginx.

iirc, openssl 1.0.1e should be able to provide tls 1.2, so
it seems quite strange
