go - Built-In source code location

Question

Where in Go's source code can I find their implementation of make.

Turns out the "code search" functionality is almost useless for such a central feature of the language, and I have no good way to determine if I should be searching for a C function, a Go function, or what.

Also in the future how do I figure out this sort of thing without resorting to asking here? (i.e.: teach me to fish)

EDIT P.S. I already found http://golang.org/pkg/builtin/#make, but that, unlike the rest of the go packages, doesn't include a link to the source, presumably because it's somewhere deep in compiler-land.
