No xrate function available

As said in the Grafana issue, xrate function doesn't exists when I compile your fork.

go get github.com/free/prometheus
git checkout xrate_v2.2.1
make build

Looking at the version output, it's the right version:

# ./prometheus --version
prometheus, version 2.2.1 (branch: xrate_v2.2.1, revision: f3e781a5af599a76edbf1c2f61a4a57ce48b371d)

When trying to run xrate function, I get the error unknown function:

rate(node_cpu{instance="host"}[60s])
Error executing query: parse error at char 6: unknown function with name "xrate"

How are you running the query? I tried by going to localhost:9090 and running the query there.

Regardless, I just figured out how to build binaries for the full range of platforms that Prometheus supports (just do promu crossbuild) and I'll make a proper release with what are (at least for me) working binaries.

Just finished an official (whatever that means) release of Prometheus 2.2.1 + xrate(): https://github.com/free/prometheus/releases/tag/v2.2.1

As the name suggests, this is exactly Prometheus release 2.2.1 plus the xrate()/xincrease()/xdelta() functions.

I was running my queries the same way you did. Weird:)

Anyway, I downloaded your release and it's working now, yeey. Off to check some graphs with the new function.

Thanks for the help
