Best way to update RTEMS?

[Gedare Bloom]

After pulling, it is a good idea to:
1. re-run bootstrap, in case any of the autoconf input files have
changed (Makefile.am, preinstall.am, configure.ac).
2. re-run configure, in case bootstrap changed any of the autoconf
output files (configure, Makefile.in)
3. re-run make, in case configure changed any of its outputs (Makefile)

The cleanest thing to do is to delete your build directory--where you
previously have run configure and make, which should not be the same
as your source (rtems.git) directory.

I decided to update from the git repo, and can't seem to get it rebuilt correctly. What are the correct steps to update my libraries after pulling down from the repo?
