A full rustc build now fails after building stage 2 compiler & standard libray. The built stage 2 compiler & libray can be installed as rustc-tiny. Rustc-tiny can then be used to complete the full build of rustc.

# HOW TO EDIT THIS FILE:
|
|
# The "handy ruler" below makes it easier to edit a package description. Line
|
|
# up the first '|' above the ':' following the base package name, and the '|'
|
|
# on the right side marks the last column you can put a character in. You must
|
|
# make exactly 11 lines for the formatting to be correct. It's also
|
|
# customary to leave one space after the ':' except on otherwise blank lines.
