Author: bdrewery Date: Tue May 9 20:21:58 2017 New Revision: 318106 URL: https://svnweb.freebsd.org/changeset/base/318106 Log: Support -DWORLDFAST to skip all build steps up to 'libraries' and 'everything'. This allows for building the world against the already-created host/sysroot environment. It is not overly useful outside of cases of large-impact changes such as a testing a new compiler. It will allow quickly getting back to an error in the target-phases of the build where a new compiler is being used.
