Alex Crichton 47ece1fa2c Don't use -Z prefer-dynamic at stage0 
This is blocking a snapshot because the stage0 target compiler comes from a
stage1 host compiler. This means that the stage0 compiler doesn't actually
understand the -Z prefer-dynamic flag and is dying as a result.

This will get added back to stage0 after a snapshot.

# except according to those terms.
# An explanation of how the build is structured:
#
# There are multiple build stages (0-3) needed to verify that the
# compiler is properly self-hosting. Each stage is divided between
# 'host' artifacts and 'target' artifacts, where the stageN host
# compiler builds artifacts for 1 or more stageN target architectures.
# Once the stageN target compiler has been built for the host
# architecture it is promoted (copied) to a stageN+1 host artifact.
#
# The stage3 host compiler is a compiler that successfully builds
# itself and should (in theory) be bitwise identical to the stage2
# host compiler. The process is bootstrapped using a stage0 host
# compiler downloaded from a previous snapshot.
#
# At no time should stageN artifacts be interacting with artifacts
# from other stages. For consistency, we use the 'promotion' logic
# for all artifacts, even those that don't make sense on non-host
# architectures.
#
# The directory layout for a stage is intended to match the layout
# of the installed compiler, and looks like the following:
#
# stageN - this is the system root, corresponding to, e.g. /usr
# bin - binaries compiled for the host
# lib - libraries used by the host compiler
# rustlib - rustc's own place to organize libraries
# $(target) - target-specific artifacts
# bin - binaries for target architectures
# lib - libraries for target architectures
#
# A note about host libraries:
#
# The only libraries that get promoted to stageN/lib are those needed
# by rustc. In general, rust programs, even those compiled for the
# host architecture will use libraries from the target
# directories. This gives rust some freedom to experiment with how
# libraries are managed and versioned without polluting the common
# areas of the filesystem.
#
# General rust binaries may stil live in the host bin directory; they
# will just link against the libraries in the target lib directory.
#
# Admittedly this is a little convoluted.
