This requires some small changes in the stdenv, then working around the weird choice LLVM made to hardcode @rpath in its install name, and then lets us remove a ton of annoying workaround hacks in many of our Go packages. With any luck this will mean less hackery going forward.

## The "build" "host" "target" terminology below comes from GNU Autotools. See

## its documentation for more information on what those words mean. Note that

## each should always be defined, even when not cross compiling.
|
|
##
|
|
## For purposes of bootstrapping, think of each stage as a "sliding window"
|
|
## over a list of platforms. Specifically, the host platform of the previous
|
|
## stage becomes the build platform of the current one, and likewise the
|
|
## target platform of the previous stage becomes the host platform of the
|
|
## current one.

, # The platform on which packages are built. Consists of `system`, a
|
|
# string (e.g.,`i686-linux') identifying the most import attributes of the
|
|
# build platform, and `platform` a set of other details.
|
|
