Cannot pass `stderrthreshold` as environment variable

[daravi]

I am able set FLAGS_stderrthreshold in code (while logtostderr and alsologtostderr are left as default) and see desired behavior. i.e. all available logs go to file and anything at or above the threshold also goes to stderr.

However when setting GLOG_stderrthreshold=<lvl> environment variable it's as if I am not setting this variable at all. It seems like for some reason this environment variable is not being correctly picked up by GLOG.

I have the same issue here. Both DLOG and LOG does not work. It seems to be stuck at level 2.
