Subject: [PATCH] [build] add option to build 1.2 alone (#5364)

Currently script/test can only build 1.2 together with 1.1. This
commit adds support to build 1.2 alone. And when THREAD_VERSION=1.2
and INTER_OP=1 are both set, both versions would be built. Sometimes
we only want to build 1.2. This would save some time for us.
