# Here are additions to the top-level Makefile by David A. Wheeler
# Unfortunately, "make bootstrap" doesn't permit enough control over
# the build process.  So we'll add new targets to allow finer control, e.g.,
# stage1_build, stage2_build, stage3_build.  See the bootstrap rules above.

# E.G., "make all-bootstrap", "make stage1_build", "make runtime-libraries"
# re-build libiberty, "make stage2_build", "make stage3_build"
